WA1885 SQL and Application Programming Training and Courseware
|
|
First, the concepts of DB2 are presented and discussed. The Structured Query Language (SQL) is presented as the means to access DB2 data (and to create and secure DB2 components). Several guided, hands-on, practice sessions give each attendee an opportunity to use SQL to access data. QMF and/or SPUFI are used to execute SQL statements. Referential Integrity concepts and implementation are covered.
DB2 (SQL) programming / embedding SQL in a COBOL application program is presented and discussed in detail. A "shell" program is modified to SELECT a single row, FETCH multiple rows, INSERT, UPDATE, and DELETE row(s), use Referential Integrity, and use column functions and grouping.
DB2 performance guidelines are discussed. The SQL statement EXPLAIN PLAN is used to help to evaluate the efficiency of SQL statements.
The following “Release Dependent” features can be covered as needed –
- Version 8 – Table-Controlled Partitioning, Common Table Expression, Dynamic Scrollable Cursors, multi-row FETCH and INSERT, GET DIAGNOSTICS, Recursive SQL, Sequence Objects, Scalar Full Select, Select Statement In An Insert statement, Delimited LOAD / UNLOAD, MQT’s
- Version 9 – PureXML, New Data Types - bigger BINARY, VARBINARY, BIGINT, DECFLOAT, INSTEAD OF triggers, INTERSECT and EXCEPT, TRUNCATE Statement, MERGE Statement, Native SQL Stored Procedures, Optimistic Concurrency Control, Automatic Object Creation, Skip Locked Data, REOPT (AUTO)
- Version 10 - Preview

After completing this course, the student should be able to:
- Explain DB2 concepts, terminology and components
- Discuss the Primary Key (PK), Unique Key (UK) and Foreign Key (FK) concept
- SELECT rows of data from DB2 tables
- Use QMF and/or SPUFI to "run" SQL statements
- Use the WHERE clause to SELECT specific rows of a DB2 table
- Build queries using the ORDER BY, GROUP BY, HAVING clauses
- Use the CASE expressions and several SCALAR / COLUMN FUNCTIONS
- Access multiple tables - JoiN, UNION, sub-queries, nested table expressions
- create Tables, Indexes, Views
- "Change" tables using the INSERT, UPDATE, DELETE statements
- Describe the security provided by the GRANT and REVOKE
- Discuss the design considerations of Referential Integrity
- Perform DCLGENs to build table definitions and I/O areas
- Modify a "shell" program to select a single row, multiple rows, and change rows
- Discuss the importance of the SQLcode and how to test for it
- Discuss overall DB2 performance considerations
- Run the EXPLAIN PLAN or VISUAL EXPLAIN and analyze results
