    DB2 Security with full the Trimmings | killexams.com true questions and Pass4sure dumps

    DB2 Security with full the Trimmings

    At a major original England-area insurance provider, a database engineer who asked not to breathe identified in this article, describes the management of security for her mainframe databases as "a nearly-impossible, labor-intensive task - if full they had to expend were IBM's own security administration utilities."

    She reports that her company has over 600 IBM DB2 databases running in 13 LPARs across eight mainframes distributed across two, geographically divide data centers.

    "About 8,000 linger users at the company hold controlled access to the literally hundreds of volumes of DB2 data on systems which they are migrating to DB2 version 5.1. They are too in the process of migrating from [IBM] MVS to the OS/390 operating system to achieve Year 2000 compliance," says the engineer.

    "While IBM did a worthy job with DB2, its security administration tools are inadequate to retain up with the changes that occur in their environment on an almost daily basis: changes in user access, the maintenance of expostulate security and the securing of access to original transactions. Their database administrators (DBAs) would breathe spending full of their time just doing security work if full they had were DB2's own security utilities. It is just not an option not to hold a second [security] administration package for DB2."

    To enhance the security administration capabilities delivered with IBM DB2, the engineer reports that her company uses RC/Secure from Platinum Technology Inc. (Oakbrook Terrace, IL). With RC/Secure, she says, "We can let their security administration personnel conclude the busywork of [granting and revoking access to DB2 database objects], while letting the DBAs focus on the intelligence work of database design. Platinum's product provides for cleaner security operations and productivity improvements over aboriginal DB2 security applications."

    In DB2's defense, the engineer concedes that her company has not looked closely at any changes in DB2 security delivered with the original version of the IBM database. Platinum's RC/Secure has become a fixture at the company over a period of years and she has diminutive incentive to change something that works.

    DB2 Security: An break to Enhance

    IBM, which has delivered DB2 since its branding in 1994 to more than 11,000 organizations and more than 40 million linger users worldwide, has been actively evolving the product from an MVS-only mainframe database to a universal data base, according to Hershel Harris, Director of Database Technology with IBM's Software Solutions Division.

    Harris briefly recounts some watershed accomplishments in the progress of DB2. "In 1994, they released an AIX and OS/2 version of the product. In 1995, they provided a parallel edition for data warehousing and a UNIX edition for Sun Microsystems and Hewlett-Packard. In 1997, they released the Universal Database (UDB) edition, adding expostulate extensions, champion for OLAP and OLTP applications and additional champion for parallel databases that enabled data to breathe split across multiple nodes in a clustered environment. This year, they announced OS/390 DB2 UDB. Version 6, which should breathe available in 1999, extends the capability of UDB to understand objects. The family of products now runs across multiple operating environments, including NT, UNIX, OS/390, AIX and other flavors of UNIX. They are no longer a only mainframe product, but they are proud of their mainframe heritage."

    Built around the relational database model, says Hershel, DB2 delivers "built-in security based on privileges." He explains that, for every user with a telling ID or group membership, DB2 DBAs can expend the product's aboriginal security features to control what the user can conclude with the database objects.

    "This goes beyond access. For every expostulate and every user, specific privileges can breathe set up, including read, write, delete, update and run. The objects can breathe tables, views or procedures, and the privileges can breathe defined at a very granular level."

    Hershel says that generic SQL data control language statements such as concede and REVOKE may breathe used readily to control expostulate access. He adds that IBM will develop available in Version 6 of the OS/390 DB2 UDB product a suite of Administrative Tools similar to those that already ship with distributed platform versions of the product, "We hold in Version 5.2 [of their distributed systems product], an easy-to-use, NT-based Administration tool that allows both graphical and Web-based administration of full distributed DB2 servers. This tool set is being added to [our OS/390 DB2 product] with its release in 1999."

    Hershel is cognizant of the availability and expend of third party products in conjunction with the IBM database, which he describes as "complimentary to the product."

    "IBM encourages complimentary product progress by other companies. In the belt of DB2 security administration, there are probably a number of companies that deliver products to enhance the capabilities delivered with DB2. These tools may provide a graphical user interface to security administration using IBM's application programming interface. Some products emphasize enhanced query capabilities or enhanced reporting. Some try to integrate system plane security with DB2. One company showed me a demonstration recently of an application that enabled speech recognition technology and its expend with DB2 database security administration. In general, they are very supportive of these efforts."

    Opportunities to enhance DB2 in a complimentary manner hold been exploited by numerous companies, including Platinum Technology, according to Pete Peterson, Vice President for Database Administration Products at Platinum.

    Peterson says that RC/Secure answers a need within companies to simplify the model for managing authority, "With DB2 version 5, IBM allows RACF or external security products to breathe used in administering security within DB2. It is not a very straightforward procedure and it is difficult to create application and user domains using IBM utilities. Companies can gain a lot of [security administration efficiency] if they had a simple way to pass a hierarchy of privileges from one user to another without having to redo everything."

    RC/Secure, according to Peterson, is designed as a "management layer on top of DB2 - but not a run-time layer." He explains that changes made to security privileges may breathe applied on an ad hoc basis or in batch mode and suggests that the latter method continues to breathe preferred by security administrators. He adds that Platinum's RC/Query product too enhances DB2's query facilities and may breathe employed in connection with RC/Secure to verify updated objects within user and application domains.

    Peterson anticipates a continuing demand for DB2 enhancement products despite IBM's pretension that Version 6 will eliminate the need for unavoidable types of enhancement products. Says Peterson, while IBM is trying to coast toward a goal of a Universal Database to enable administration across platforms, "there are differences in the mainframe DB2 product that were build there to cater to the MVS folks and to capitalize on the characteristics of that platform that will continue to impede this goal."

    Computer Associates: Enhancement Equals Replacement

    Mark Combs agrees that IBM opened doors to third parties with version 5 of its DB2 implementation on MVS. Combs, who is Senior Vice President for Research and progress with Computer Associates (CA) in Islandia, NY, sees the break created less in terms of enhancing DB2 than as an break to supplant RACF with either ACF2 or Top clandestine - both CA mainframe security management products.

    "Companies need to coast to real, rules-based security - that is, a situation in which industry rules determine access. Today, in many mainframe environments, about 75 percent of the rules are controlled by system management products such as CA-ACF2, CA-Top clandestine or RACF from IBM. Another 25 percent are actually established or enforced using much less robust SQL database security capabilities in products enjoy DB2. What is needed is an integrated management infrastructure that enable centralized, rules-based security across the entire environment and that provide administrative tools on the mainframe, as well as graphical user interface-based tools on the desktop," says Combs.

    Basic SQL Coding for DB2 Universal Database for OS/390 | killexams.com true questions and Pass4sure dumps

    Take a recognize at the four primary statements of DML: Select, Update, Insert, and Delete. You will learn the function each of these can play in your efforts to master DB2. You will too recognize at various aspects of SQL, a necessary language to understand though the comprehension plane will vary depending on the user's activity.

    This chapter is from the bespeak 

    In the previous chapter, they discussed the definitions of various database objects using the Data Definition Language (DDL). In this chapter, they start manipulating the database objects using the portion of SQL known as Data Manipulation Language (DML). They will breathe populating (inserting) data into the database and retrieving the data using many powerful methods. Depending on the sophistication of the database users, they can expend SQL to query the database. The majority of the SQL statements within a DB2 application involve DML statements. Therefore, application developers must understand the various methods of inserting, updating, and retrieving data from the database. They will start with simple retrieval statements and gradually introduce more intricate methods of data manipulation. The DB2 Certification database will breathe used for most of the examples. There are four main DML SQL statements they consider: SELECT, INSERT, UPDATE, and DELETE.

    SQL is based on mathematical principles, specifically on set theory and relational algebra. The data is stored in the database as unordered sets of data records. SQL is a set-oriented language, and many of its language elements are directly related to relational algebraic terms, such as permutation, projection, restriction, and join.

    A set of data is represented in a DB2 database as a table or a view and is stored in a DB2 table without respect to order. To retrieve data in a particular order, an ORDER BY phrase must breathe added to a SELECT statement. Similarly, if the data is to breathe grouped, then a GROUP BY phrase must breathe added to the statement.

    Now, let's review the DB2CERT database design defined in the previous chapter and exploit data using various SQL statements. There are three main tables: CANDIDATE, TEST, and TEST_CENTER. Each table represents a set of records that correspond to a test candidate (person), a test, and a test focus (location).

    There is an associative table, known as the TEST_TAKEN table, that is used to reflect the relationships among the three main tables. The TEST_TAKEN table is used to schedule the test candidates and too to maintain their test scores.

    NOTE

    The longest SQL statement is 32,765 bytes.

    Remember that to execute any operation, the user must hold the necessary privileges.

    Retrieving the Entire Table

    The most basic of full retrieval command involves the SELECT statement with no operators other than the cognomen of the table. This SQL statement retrieves full of the candidates who hold taken a DB2 Certification exam. The information requested is contained in the table TEST_TAKEN.

    SELECT * FROM db2cert.test_taken

    SQL is a data access language that consists of language statements and clauses. There are many optional clauses that can breathe used to modify the output. The output of a SELECT statement is known as a result set or result table. The results from the SELECT statement are shown next. In this example, using an asterisk or star character (*) for column selection, the columns will breathe returned to the user in the order in which they are defined in the table.

    CID TCID NUMBER DATE_TAKEN START_TIME FINISH_TIME SCORE PASS_FAIL SEAT_NO --- ---- ------ ---------- ---------- ----------- ----- --------- ------- 111 TX01 500 01/01/2000 11:30:00 12:30:00 65 Y 1 111 TX01 501 02/02/2000 10:30:00 11:45:00 73 Y 1 111 TX01 502 03/03/2000 12:30:00 13:30:00 67 Y 1 222 TR01 500 01/01/2000 14:00:00 15:30:00 55 N 2 222 TR01 502 01/02/2000 09:00:00 10:15:00 53 N 2 222 TR01 502 02/18/2000 10:00:00 11:30:00 75 Y 2 333 TX01 500 03/01/2000 11:30:00 13:00:00 82 Y 2 333 TX01 501 12/29/2000 14:00:00 - - - 1 333 TX01 502 03/02/2000 14:00:00 14:30:00 92 Y 1 9 record(s) selected.

    In SQL, the * is used to betoken that full columns of a table are being referenced. In this example, the SQL statement refers to full of the columns defined for the DB2CERT.TEST_TAKEN table. If the table is altered and a original column is added to the table definition, the result set would contain the original column.

    NOTE

    Adding a original column to an existing table will result in default values being populated for the existing rows.

    Since the output of the SQL statement using * character varies according to the table definition, it is recommended that you specify full of the column names you want to see in the SELECT statement. They could hold obtained the same result as the statement using SELECT * with the following SQL statement.

    SELECT cid, tcid, number,date_taken,start_time, finish_time,score,seat_no FROM db2cert.test_taken;

    NOTE

    The * character is used to advert to full of the columns defined for a table. The order of the columns in the result table is the same order as specified in the CREATE TABLE or CREATE VIEW statement.

    What is returned to the user is known as the result set. If the result set is big it is advisable to breathe confident to filter the data using a WHERE predicate.

    The FROM clause is required for the DML SQL statement, since it describes the location (table or view) of the data. Their sample references a unique table called DB2CERT.TEST_TAKEN. The SELECT and FROM clauses are required in full data retrieval statements. The list of columns following the SELECT keyword is referred to as the select list.

    Projecting Columns from a Table

    Projection is a relational operation that allows you to retrieve a subset of the defined columns from a table. The next sample restricts the output from the SELECT command so that only the candidate ID, test center, and test number attributes from the TEST_TAKEN table are shown.

    SELECT cid,tcid,number FROM db2cert.test_taken

    The output of this SELECT statement is shown below.

    CID TCID NUMBER --- ---- ------ 111 TX01 500 111 TX01 501 111 TX01 502 222 TR01 500 222 TR01 502 222 TR01 502 333 TX01 500 333 TX01 501 333 TX01 502 9 record(s) selected.

    The order of the columns in the result table will always match the order in the select list. The order of the columns as they were defined in the CREATE TABLE or CREATE VIEW statement is ignored when a select list is provided in the SQL statement. In this example, the order of the columns is similar to the order in the CREATE TABLE statement, since the CID column was defined prior to TCID and NUMBER columns.

    Changing the Order of the Columns

    Permutation is the relational operation that allows you to change the order of the columns in your result table. Permutation is used every time you select columns in an order different than the order defined in the CREATE TABLE statement. For example, to array the test focus ID prior to the candidate IDs and the test number, you could execute the following:

    SELECT tcid,cid,number FROM db2cert.test_taken

    The result of this SELECT statement specifies a select list in a different order than was defined in the table definition.

    TCID CID NUMBER ---- --- ------ TX01 111 500 TX01 111 501 TX01 111 502 TR01 222 500 TR01 222 502 TR01 222 502 TX01 333 500 TX01 333 501 TX01 333 502 9 record(s) selected.

    NOTE

    We advert to the output of a SELECT statement as the result table because the output of full SELECT statements can breathe considered a relational table.

    Restricting Rows from a Table

    Restriction is a relational operation that will filter the resulting rows of a table. Restriction can breathe accomplished through the expend of predicates defined in a SQL WHERE clause. To restrict the result set, they need to add a WHERE clause to the SQL statement.

    NOTE

    A predicate is a condition placed on the data. The result of the condition is TRUE, FALSE, or UNKNOWN.

    The WHERE clause specifies conditions or predicates that must breathe evaluated by DB2 before the result table is returned to the linger user. There are many telling types of predicates that can breathe used. In the following example, the equality (=) predicate is used to restrict the records to only those candidates who hold taken a DB2 Certification test at the test focus TR01.

    SELECT tcid,cid FROM db2cert.test_taken WHERE tcid ='TR01'

    The WHERE clause too accepts other comparison operators, such as greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), and not equal to (<>).This statement is an sample of a basic predicate. A basic predicate compares two values. In addition, more intricate predicates, such as LIKE, BETWEEN, and IN, are too telling and will breathe discussed later.

    NOTE

    Trying to execute this sample SQL statement will result in a data type compatibility error, because the column TCID is defined with a user-defined data type (UDT).

    Predicate Evaluation for UDTs

    The column TCID was defined as a user-defined data type. To develop the comparison in the WHERE clause valid, a casting function needs to breathe used. This is not mandatory if the comparison is to a literal or host variable. This technique is however demonstrated below:

    SELECT tcid, cid FROM db2cert.test_taken WHERE tcid=CAST('TR01' AS db2cert.center_id)

    Predicate evaluation requires that the data types breathe compatible (same data type or a compatible data type). They can accomplish the data type conversion (cast) using one of two methods:

  • Use the CAST expression.
  • Use a casting function.
  • Refer to Chapter 15, "Object Relational Programming," for more information on casting for UDTs.

    NOTE

    Although not always mandatory, casting is recommended to ensure compatible data types are compared, including length and scale. This allows DB2 to resolve these as indexable rather than stage 2 predicates.

    Restricting Rows Using Multiple Conditions

    It is workable to combine multiple conditions (predicates) in a unique SQL statement. The predicates can breathe combined using Boolean operators, such as the AND or OR operators. These operators allow you to combine multiple conditions in a unique SQL statement. The order of the predicate evaluation will not strike the result set (known as set closure).

    The next sample retrieves the records for the test candidates who took a test at test focus TR01 and achieved a score greater than 65. The rows that meet the predicates are known as the qualifying rows. The following sample is an SQL statement using multiple predicates:

    SELECT tcid,cid,score FROM db2cert.test_taken WHERE tcid= CAST('TR01' AS db2cert.center_id) AND score > 65 Selecting Columns from Multiple Tables

    There are basically two operations that combine columns from multiple tables in a unique SQL statement. These operations are

    Cartesian Product

    A Cartesian product is a relational operation that will merge full the values from one table with full the values from another table. This operation is not used frequently because the result table can breathe very large. The number of rows in the result table is always equal to the product of the number of rows in the qualifying rows for each of the tables being accessed.

    NOTE

    The DB2 optimizer may select to utilize a Cartesian product of unrelated tables if this is deemed to breathe an efficient method of accessing multiple tables. An sample would breathe two single-row tables that are joined with a big table. The cross-product of 1 ∴ 1 = 1; thus the big table access is deferred as late as possible, with a potential extend in the restrictive predicates that can breathe applied without incurring the overhead of a big Cartesian result. This method of table access is typical in processing queries against a star schema data model.

    The following sample is a Cartesian product of full test numbers and test names from the TEST table, with full candidates from the TEST_TAKEN table. First, select from the TEST table.

    SELECT number, cognomen FROM db2cert.test NUMBER NAME ------ -------------------------------------------------- 500 DB2 Fundamentals 501 DB2 Administration 502 DB2 Application Development 3 record(s) selected. Next select of full candidates from the test_taken table. SELECT cid,tcid FROM db2cert.test_taken CID TCID --- ---- 222 TR01 222 TR01 222 TR01 111 TX01 111 TX01 111 TX01 333 TX01 333 TX01 333 TX01 9 record(s) selected.

    Then combine the two tables to profile a Cartesian product result table.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test NUMBER CID TCID ------ --- ---- 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 27 record(s) selected.

    There are two tables referenced in the FROM clause of this query. The tables are separated by commas. There is no relationship expression in the WHERE clause. This type of query results in a Cartesian product.

    The result table is a representation of full workable combinations of the input tables. The TEST table has three rows, and the TEST_TAKEN table has nine rows. Therefore, the SELECT statement shown above returns 27 rows. Note the first column cognomen in this query. It is necessary to fully qualify the column cognomen by providing the schema cognomen and table cognomen with the column cognomen because this column exists in both the TEST table and TEST_TAKEN table. In this case, they needed to specify that the NUMBER column is to breathe retrieved from the DB2CERT.TEST_TAKEN table and not from the DB2CERT.TEST table.

    By adding a predicate to a Cartesian product SQL query, the result table can represent a more useful representation of the data. In the sample below, the query represents full of the tests that were taken by the candidate whose ID is 111.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test WHERE cid='111' NUMBER CID TCID ------ --- ---- 500 111 TX01 500 111 TX01 500 111 TX01 501 111 TX01 501 111 TX01 501 111 TX01 502 111 TX01 502 111 TX01 502 111 TX01 9 record(s) selected.

    Adding a WHERE clause to your query does not always provide the desired result. In the sample shown above, you want to know full of the tests that were taken by the candidate whose ID is 111, and the query returns nine rows. But they know from previous queries that the candidate took only three tests. The query in the sample above has a WHERE clause to filter out the candidate whose ID is 111 from the TEST_TAKEN table, but there was no filter on the TEST_CENTER table. Therefore, the result of the query would always breathe a multiple of the number of testing centers. Usually, when multiple tables are referenced, you should involve a cross-table relationship using a table merge or join method, as shown in the following example. They will examine table join methods further in the next section.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test WHERE cid= '111' AND db2cert.test_taken.number=db2cert.test.number NUMBER CID TCID ------ --- ---- 500 111 TX01 501 111 TX01 502 111 TX01 3 record(s) selected.

    To avoid data redundancy, it is recommended that the database tables breathe normalized. Following a normalization process, a number of related tables will exist. To meet some of the required queries, the tables must breathe reconstructed. The tables are reconstructed temporarily, using a table join strategy to relent a single-result table.

    The result tables in the previous examples usually provided candidate ID numbers and not the complete cognomen of the test candidates. The candidate IDs are stored in the TEST_TAKEN table, and the full names are stored in the CANDIDATE table. To obtain the cognomen of a candidate, the data must breathe retrieved from the CANDIDATE table, using a relationship or join strategy.

    Consider an sample that will list the names and phone numbers of candidates who were registered to win a DB2 Certification test in 2000. To accomplish this, they need to select data from two different tables:

  • db2cert.candidate
  • db2cert.test_taken
  • Let's retrieve a list of candidate names, phone numbers, and IDs from the CANDIDATE table. The candidate names were stored in multiple columns to allow for smooth retrieval by last name.

    SELECT fname,initial,lname,hphone,cid FROM db2cert.candidate

    The output of this sample follows. Pay special attention to the values in the CID column. It will breathe used as the join column in the next example.

    FNAME INITIAL LNAME HPHONE CID -------- ------- ---------- ---------- --- Bill B Wong 1115551234 111 George Baklarz 2226543455 222 Susan M Visser 4442314244 333 Glen R Sheffield 5552143244 444 Jim G Stittle 6662341234 555 Kevin W Street 7773142134 666 Bert F Nicol 8886534534 777 Paul C Zikopoulos 9992112212 888 8 record(s) selected.

    Now, let's retrieve the ID numbers of those candidates who were registered to win the test in 2000.

    SELECT divide cid FROM db2cert.test_taken WHERE YEAR(date_taken) = 2000 CID --- 222 111 333 3 record(s) selected.

    The candidate IDs in the TEST_TAKEN table must correspond to a candidate ID in the CANDIDATE table because of the declarative referential integrity constraints. The parent table in the relationship is the CANDIDATE table and the child table (dependent table) is the TEST_TAKEN table.

    The result table from the above query does not involve the test candidate 444, since that candidate did not hold a test scheduled for 2000. They need to join the two result tables based on the candidate ID values. This column is known as the join column.

    NOTE

    Query performance can significantly help if the join columns are appropriately indexed.

    The following unique query will meet the end-user requirement.

    SELECT divide fname,initial,lname,hphone FROM db2cert.test_taken,db2cert.candidate WHERE YEAR(date_taken) = 2000 AND db2cert.test_taken.cid=db2cert.candidate.cid

    A table join requires a predicate that includes an expression based on columns from the tables referenced in the FROM clause. This is known as a join predicate. The FROM clause has not changed from the Cartesian product examples. The only disagreement is in the join predicate (test_taken.cid = candidate.cid).

    NOTE

    An alternative profile of the FROM clause for joins involves explicitly coding the join keyword between the tables (rather than using a comma) and coding the join predicates in the ON clause rather than in the WHERE clause. This method of coding will breathe covered in more detail in Chapter 4, "Advanced SQL Coding."

    The table names needed to breathe explicitly stated because there is a column named CID in both of the referenced tables. When multiple tables are being accessed in a unique query, any selected columns that occur in more than one table must breathe qualified with the table name.

    NOTE

    An mistake will occur if the columns being referenced are obscure (not properly qualified).

    The maximum number of groundwork tables that can breathe in a unique SQL statement is 225; however, you are limited to 15 tables in a join (the FROM clause).

    NOTE

    The 15-table restrict can breathe increased by updating the macro SPRMMXT to a value greater than 15.

    This kindly of join operation shown in the above sample is too known as an inner join. An inner join displays only the rows that are present in both of the joined tables.

    Using Correlation Names

    If each of the columns needed to breathe fully qualified with the table name, such as tableschema.tablename.columnname, the queries would become very big and cumbersome to work with. Fortunately, there is an easier way to qualify the obscure columns resulting from a multitable SELECT statement.

    The columns can breathe qualified using a correlation name. A correlation cognomen is a temporary alias for the tables referenced in an SQL statement. They rewrite the previous query using correlated names as follows:

    SELECT divide fname,initial,lname,hphone FROM db2cert.test_taken tt, db2cert.candidate c WHERE YEAR(date_taken) = 2000 AND tt.cid = c.cid

    The correlation cognomen immediately follows the cognomen of the table as stated in the FROM clause. In this example, the correlated cognomen for the TEST_TAKEN table is tt, and the correlated cognomen for the CANDIDATE table is c.

    NOTE

    Correlation names can breathe optionally prefixed with the AS keyword, such as DB2CERT.CANDITATE AS C. This is purely for readability.

    The correlated names are accessible within the SQL statement only. Following the execution of the SQL statement, the correlation cognomen is no longer defined. Once a correlation cognomen has been defined, it can breathe referenced in the leisure of the query instead of the table name. However, the table cognomen can quiet breathe referenced.

    NOTE

    Use simple, easy-to-remember correlation names. Table initials are well-behaved candidates for correlation names.

    Sorting Your Output

    We hold been retrieving data from one or more tables. The order of the result table has not been specified in any of the SQL statements. Therefore, the data is retrieved in an undetermined order if there is no ORDER BY clause in the SQL statement.

    NOTE

    The only guaranteed way to revert data in the required sequence is with the ORDER BY clause. Any data retrieval that is currently returned in sequence without this clause is purely based upon the data retrieval method at the time. A future access path change may not revert the data in the same sequence.

    The following sample produces a list of the test candidates in alphabetical order by last cognomen for the candidates who hold taken a DB2 Certification test at the TR01 test center.

    SELECT lname,initial,fname FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid='TR01' ORDER BY lname

    This sample contains a original clause, ORDER BY. After the ORDER BY clause, you can list the columns that will specify the sort order and the type of sort.

    NOTE

    Appropriate indexing may allow DB2 to avoid sorting the data to match the ORDER BY clause. If the data is already sequenced via the index, DB2 may select to utilize the index and avoid sorting the data. DB2 cannot avoid a sort for an ORDER BY involving columns from more than one table. Where possible, involve columns from only one table in the ORDER BY to give DB2 greater break for sort avoidance.

    The SQL can breathe modified so that the output is changed to descending order by last cognomen and a secondary order column on the first cognomen in ascending order.

    SELECT lname,fname,hphone FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid= 'TR01' ORDER BY lname DESC, fname

    In this example, the DESC keyword that follows the lname column indicates that the result table should breathe in descending order based on the last name. More than one record can hold the same last name. This situation is quite common. There is a second column specified in the ORDER BY clause, fname. There is no keyword specifying the sort sequence based on the fname column. Therefore, the default ordering sequence (ascending) is used.

    The next sample contains three columns lname, fname, and hphone. You can reference the column that should breathe used to sort the data using the column cognomen or by specifying its position in the select list. Using the column position is useful when the column in the select list is made up of derived columns (calculated columns) that hold no categorical name.

    SELECT lname,fname,hphone FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid='TR01' ORDER BY 1 DESC, 2

    In this example, the sort order is specified using the column position. Therefore, the query result is exactly the same as the in previous example.

    You can too assign an alternative column cognomen using column renaming. The assigned cognomen can then breathe referenced in the ORDER BY clause, and it appears as the column heading where appropriate.

    NOTE

    Although useful, coding a column position rather than a column (or renamed column) in the ORDER BY clause may lead to a different sequence if another column is inadvertently added to the query that alters the column positioning.

    The ORDER BY clause must succeed full subselects in the FULLSELECT statement. The only clauses that can succeed the ORDER BY clause are the for FOR FETCH ONLY, FOR READ ONLY, OPTIMIZE, WITH QUERYNO, FETCH FIRST n ROWS clauses.

    Derived Columns

    There are some cases when you will need to effect calculations on the data. The SQL language has some basic mathematical and string functions built in. Mathematical operations involve measure addition, subtraction, multiplication, and division.

    The calculation can breathe defined in the WHERE clause of the SQL statement or the select list. Suppose that you need to cipher a passing rate for a DB2 test. The passing rate is defined as the percentage of candidates that pass the test (totalpassed*100/totaltaken). The following SQL statement will accomplish this for us for test number 500:

    SELECT number, totalpassed*100/totaltaken FROM test WHERE number='500'

    In this example, the second column of the output list is a calculated column. recollect that you must expend the column position if you want to expend this calculated column for the ORDER BY clause unless you cognomen it (as they now discuss).

    NOTE

    Occasionally, the results of a derived column may not array as expected. The sample using totalpassed*100/totaltaken will result in a value of 66 being retrieved. Since both the totalpassed and totaltaken columns are integers, the final result is too an integer, and the fractional Part is discarded. If this is not your desired result, you should expend other functions (like decimal) to change the way the calculation is performed or displayed.

    Naming Derived/Calculated Columns

    You can specify a column cognomen for any expression. When you provide the derived (calculated) column with a name, the ORDER BY clause can reference the derived cognomen to allow for a more readable SQL statement.

    The following SQL calculates the percentage of people that hold passed the DB2 Certification exams and orders the output in descending order of the passing rate.

    SELECT number,totalpassed*100/totaltaken AS PassedRate FROM test ORDER BY PassedRate DESC

    The AS clause is used to rename the default cognomen of an element in the select list. In this example, they are giving the cognomen of PassedRate to the result of the division of columns totalpassed by totaltaken. The named column is used in the query to specify the column that should breathe used for sorting the output.

    NOTE

    The AS keyword is optional, although it should breathe added for readability. Without the AS clause, it may breathe unclear whether the goal was to rename a column or a comma was missed between two retrieved columns.

    Functions

    In DB2, there are different types of functions provided. For example, two types of functions provided by DB2 are scalar and column functions (a third type of function called a table function is discussed in Chapter 15, "Object Relational Programming."

  • Scalar functions (also known as row functions) provide a result for each row of the result table. A scalar function can breathe used any region an expression is allowed.

  • Column functions (also known as vector functions) work with a group of rows to provide a result. The group is specified using a FULLSELECT and optionally grouped using the GROUP BY clause.

  • In this section, they introduce you to some of the SQL functions provided with DB2. SQL functions are categorized by their implementation type. Either the functions are built in or they are extensions of DB2 and are known as user-defined functions (UDFs).

  • Built-in functions are defined within the SQL standards, and they are provided by DB2. These can breathe either scalar or column functions.

  • UDFs are not defined within the SQL standards because they are extensions of the current SQL language. These functions can breathe developed by a DB2 administrator or application developer. UDFs can breathe either scalar or table functions, but not column functions. Once the UDFs hold been created, they can breathe invoked by any linger user with the proper privileges. For more information about UDFs, advert to Chapter 15.

  • Scalar Functions

    Scalar functions are applied to each row of data, and there is a per-row result provided. If they want to retrieve only the first three digits of telephone numbers for each candidate, they could expend a scalar function. The function that is used is called SUBSTR. The arguments for this function involve a string data type column, a soar offset, and length. The output data type and advert of the function depend on the input data type and attribute. The following sample retrieves the telephone belt code for the column wphone.

    SELECT lname, SUBSTR(CHAR(wphone),1,3) FROM db2cert.candidate

    The SUBSTR function is a scalar function. In this example, SUBSTR returns a character string of three characters. The result string corresponds to the first three characters of the wphone column. This function is known as a string function because it works with any string data type. If they wanted to provide the output column with a meaningful name, they could provide an alias, as was done for calculated columns.

    In the sample above, the substring starts from the soar of the string, because they betoken one (1) as the second parameter of the function. The length of the resulting string is indicated in the third argument. In their example, the length is three. Note that the data type of the wphone column is phone, so a casting function is used to metamorphose the phone data type to the char data type.

    The following query will provide the month when the exam was taken. The input for this function is a DATE string, and the output is an integer.

    SELECT fname, MONTH (date_taken) FROM candidate c, test_taken tt WHERE c.cid=tt.cid Column Functions

    Column functions provide a unique result for a group of qualifying rows for a specified table or view. Many common queries can breathe satisfied using column functions where they involve common tasks, such as finding the smallest value, the largest value, or the tolerable value for a group of data records. In the following sample you can obtain the maximum length of time of any of the DB2 Certification exams:

    SELECT MAX("length") FROM test

    Because the length column shares its cognomen with the length scalar function, the column cognomen is encased within double-quotes to distinguish this as a column and not a function.

    If they added a WHERE clause to this example, the maximum would represent the maximum length for the qualifying rows, since the predicate is used to filter the data prior to the application of the MAX function.

    This next sample calculates the tolerable of the number of seats for full of the test centers. Notice the column function AVG is used in this example:

    SELECT AVG(noseats) FROM test_center

    DB2 provides many more built-in functions. If you are interested in calculating statistical information, you can expend statistical functions, such as VARIANCE, STDDEV, or a sampling of these functions.

    NOTE

    MAX and MIN functions can breathe either column or scalar functions depending on the input arguments.

    Grouping Values

    Many queries require some plane of aggregated data. This is accomplished in SQL through the expend of the GROUP BY clause. The following SQL obtains the tolerable number of seats for each country:

    SELECT country, AVG(noseats) FROM test_center GROUP BY country

    This SQL statement obtains the tolerable number of seats per country, and the GROUP BY clause tells DB2 to group together the rows that hold the same values in the columns indicated in the GROUP BY list. In their example, they are grouping countries into subsets. As the subsets are created, DB2 calculates the tolerable of each of those groups or subsets, in this case, by each country.

    When you combine column functions and other elements, such as column names, scalar functions, or calculated columns, you must expend the GROUP BY clause. In this case, you must involve every element that is not a column function in the GROUP BY list. The only elements that can breathe omitted in the GROUP BY list are constant values.

    The next SQL statement obtains a list that includes the tolerable slit score and minimum test length for the DB2 Certification exams. They group this list by the type of exam, as follows:

    SELECT type, AVG(cut_score), MIN("length") FROM test GROUP BY type

    NOTE

    Appropriate indexing can allow DB2 to avoid a sort to group the data rows to match the GROUP BY clause.

    It is workable to sort the output of the previous sample using an ORDER BY clause.

    NOTE

    GROUP BY may revert data in the same order as an ORDER BY, but this is not guaranteed and is based upon the access path. The only method to guarantee data sequence is with an ORDER BY.

    Restricting the expend of Sets of Data

    Up to now, they hold discussed how to restrict output based on row conditions. With SQL, it is too workable to restrict that output using column functions and the GROUP BY clause. Suppose you want a list of full the test centers that hold administered more than five DB2 Certification exams. To develop it easier to understand, let's first secure the number of tests that hold been taken in each test center.

    SELECT tcid, count(*) FROM test_taken GROUP BY tcid

    We expend the count column function to secure the total number of tests that hold been taken in each test center. When you expend an asterisk (*) with the count function, you are indicating that you want the number of rows in a table that meet the criteria established in the SQL statement. In this example, they are grouping by TCID because they hold a number of occurrences for full the test centers in the TEST_TAKEN table. The TEST_TAKEN table has an entry for every DB2 Certification exam that has been taken. Finally, the output is restricted to only those test centers that hold administered more than four exams.

    SELECT tcid FROM test_taken GROUP BY tcid HAVING COUNT(*) > 4

    This sample introduces the HAVING clause. The HAVING clause is equivalent to the WHERE clause for groups and column functions. The HAVING clause will restrict the result set to only the groups that meet the condition specified in it. In their example, only the test centers that hold administered more than four DB2 Certification exams will breathe displayed.

    Eliminating Duplicates

    When you execute a query, you might secure duplicate rows in the admit set. The SQL language provides a special clause to remove the duplicate rows from your output. The following SQL generates a list of names and phone numbers for full the candidates who hold taken a test. In the following example, they eliminate the duplicate rows from their output list using the divide clause.

    SELECT divide fname,wphone,hphone FROM candidate c,test_taken tt WHERE c.cid=tt.cid

    The divide clause can too breathe used with the count function. When you expend divide inside a count function, it will not count the duplicate entries for a particular column. The following sample allows you to count how many different test centers hold candidates registered.

    SELECT COUNT(DISTINCT tcid) FROM test_taken

    This sample provides the number of test centers that are registered in the TEST_TAKEN table. recollect that full the candidates who hold registered for DB2 Certification exams are stored in this table. develop confident that you understand the disagreement between COUNT(*), COUNT(colname), and COUNT(DISTINCT colname). They are very similar in syntax but differ in function.

    NOTE

    COUNT(*) returns a count of full rows that qualify against the WHERE clause. COUNT(colname) returns a count of full rows that qualify against the WHERE clause, with null occurrences of colname removed. COUNT(DISTINCT colname) counts divide occurrences of colname, with nulls removed.

    Searching for String Patterns

    SQL has a powerful predicate that allows you to search for patterns in character string columns. This is the enjoy predicate. Suppose you want to generate a list of the candidates whose first cognomen starts with the letter G.

    SELECT fname,lname,wphone,hphone FROM candidate WHERE fname enjoy 'G%' ORDER BY lname,fname

    In this query, they expend a wildcard character with the enjoy predicate. In SQL, the percent character (%) is a substitute for zero or more characters. The search string G% can breathe substituted with names enjoy George, Gary, Ginger, and so on (since the percent character can substitute zero or more characters, the search string can too breathe a unique letter G).

    The percent character can breathe used any region in the search string. It too can breathe used as many times as you need it. The percent symptom is not case-sensitive, so it can win the region of uppercase or lowercase letters. However, the constant characters included in your search string are case-sensitive.

    Another wildcard character used with the enjoy predicate is the underline character (_). This character substitutes one and only one character. The underline character can win the region of any character. However, the underline character cannot breathe substituted for an barren character.

    NOTE

    If the pattern needs to search for occurrences of the wildcard characters % and _ as their actual values, then the evade clause is used to specify a character that precedes the percent or underscore in the pattern.

    The previous SQL can breathe modified to involve full candidates' names and the telephone numbers for those candidates whose cognomen has a lowercase letter "a" as its second letter.

    SELECT fname,lname,wphone,hphone FROM candidate WHERE fname enjoy '_a%' ORDER BY lname,fname

    This sample uses two wildcard characters that work with the enjoy predicate. The search string in this sample can involve names, such as Paul, Gabriel, or Natalie. (The first character may breathe any character, the lowercase letter "a" is the second character in the string, and the string ends with any number of characters.)

    NOTE

    When the pattern in a enjoy predicate is a fixed-length host variable, the revise length must breathe specified for the string to breathe returned. 'G%' assigned to an 8-byte variable (LIKE :variable) will search for full occurrences of 'G% ' (G, followed by any character, followed by 6 blank characters). To find rows that originate with a G, then 'G%%%%%%%' should breathe assigned to the fixed-length variable.

    Searching for Data in Ranges

    SQL too offers us a sweep operator. This operator is used to restrict rows that are in a particular sweep of values. respect the requirement to list those candidates whose scores in the DB2 Certification exam are between 60 and 75.

    SELECT divide fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score BETWEEN 60 AND 75

    The BETWEEN predicate includes the values that you specify for searching your data. An famous fact about the BETWEEN predicate is that it can work with character ranges as well.

    In addition to the score requirement, this sample modifies the SQL to involve only those candidates whose last cognomen begins with a letter between B and G.

    SELECT divide fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score BETWEEN 60 AND 75 AND lname BETWEEN 'B' AND 'GZ'

    In this example, the second BETWEEN predicate contains character values. They need to specify the GZ value to involve full the workable names that start with the letter G. This was done assuming that the letter Z is the last workable value in the alphabet.

    NOTE

    The arguments of the BETWEEN clause are not interchangeable; the first must specify the low value, and the second, the high value. BETWEEN 1 AND 2 will revert full values within the sweep (inclusive of 1 and 2). BETWEEN 2 AND 1 will revert zero rows.

    Searching for Null Values

    Null values represent an unknown value for a particular occurrence of an entity. They can expend a null value in the cases where they don't know a particular value of a column. Let's converse that they want a list of full those candidates whose score is not yet input. This condition is represented with a null value.

    SELECT fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score IS NULL

    The IS predicate is used to search for the null value in this example. recollect that the null value means "unknown." Because it has no particular value, it can't breathe compared with other values. You can't expend conditional operands, such as equal (=) or greater than (>), with null values.

    Searching for Negative Conditions

    The BETWEEN, IS, and enjoy predicates always recognize for the values that meet a particular condition. These predicates can too breathe used to recognize for values that don't meet a particular criterion.

    The NOT predicate can breathe used to recognize for the antithetical condition, combined with the LIKE, BETWEEN, and IS predicate, to accomplish negative searches, as shown in the following example. This sample has a enjoy predicate combined with the NOT predicate. They want a list of those candidates whose last names conclude not start with the letter S.

    SELECT divide fname,lname,wphone,hphone FROM candidate WHERE lname NOT enjoy 'S%' ORDER BY lname,fname

    The next sample has a BETWEEN predicate combined with the NOT predicate. They want the list of those candidates whose score, in any test, is not in the sweep 60 to 75.

    SELECT divide fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND integer(score) NOT BETWEEN 60 and 75

    In this example, the NOT predicate will exclude full the values that are in the sweep 60 to 75.

    Negation can too breathe applied to the null value. This SQL produces a report that searches for those candidates that hold a seat number assigned. This is expressed with a NOT NULL value.

    SELECT divide fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND seat_no IS NOT NULL

    NOTE

    The NOT operator can too breathe used to negate the measure comparison operators, =, <, <=, >, and >=.

    When dealing with nulls, NOT or negation may not revert the antithetical of the positive logic. For example, WHERE SEAT_NO = 1 will revert only the rows for seat number 1. Any value other than 1 is discarded, as these rows are FALSE, including nulls, since these are unknown. WHERE SEAT_NO <> 1 excludes rows where the seat number is 1, and too discards nulls because these are unknown.

    Searching for a Set of Values

    In SQL, it is workable to establish a restriction condition based on a set of values. Suppose that you need a list of the test centers that hold candidates registered for the DB2 Fundamentals test and for the DB2 Application progress test. This can breathe queried with the following statement:

    SELECT divide name,phone FROM test_center tc, test_taken tt WHERE tc.tcid=tt.tcid AND (number = '500' or number ='502')

    To simplify structure multiple OR conditions when multiple values for the same column are being compared, it is workable to rewrite the statement using the IN clause.

    SELECT divide name,phone FROM test_center tc, test_taken tt WHERE tc.tcid=tt.tcid AND number IN ('500','502')

    The IN clause is used to denote a set of values. In this example, they expend a constant set of values.

    You can too expend the NOT predicate with the IN clause. In this case, the condition will breathe honest when a value is not present in the set of values provided to the IN clause. You can expend as many values as you wish in the IN clause, within the defined limits of the size of a SQL statement.

    Advanced Selection Functionality

    In Chapter 4, "Advanced SQL Coding," they will recognize at more of the functionality and power of the SELECT statement. They will cover topics such as

  • Subqueries
