  DB2 concepts

identify DB2 family
explain DB2 workstation component functions
identify DB2 objects
identify the key differences between static SQL and other application alternatives for accessing DB2 data




  Exercise 1 - Data Definition Language (DDL)

use SQL Processor Using File Input (SPUFI) to execute a supplied script
create the objects that are used for the labs in this course
set up the SQL to create and populate these objects
examine the impact of referential integrity using SPUFI




  Program structure I

embed INSERT, UPDATE, DELETE and single-row SELECT statements in application programs
effectively communicate with DB2 when processing NULL values and determining the success of statement execution
demonstrate use of DB2 coding aids
code CONNECT statements within an application program
identify connection types and impacts on a unit of work




  Exercise 2 - program structure I

use DCLGEN
describe the basic flow of the supplied program skeleton
code INCLUDE statements for the SQL Communication Area (SQLCA) and DCLGEN output
declare and use host variables to provide NULL support
code WHENEVER statements to handle SQL error and warning checking
embed SQL statements in an application that will support selection of a single row of information
use elemental assignment of DB2 columns to a host variable list
use indicator variables for NULL support
embed INSERT, UPDATE and DELETE statements in an application
exploit the information in the SQLCA concerning the number of rows affected by an INSERT, UPDATE, or DELETE statement
highlight the difference between application and system defined referential constraint enforcement




  Program preparation

identify the additional steps necessary to prepare a program that contains embedded SQL for execution
describe the functions of the DB2 PRECOMPILE and BIND processes
describe factors relevant to the BIND process, including RUNSTATS positioning, package status, parameters, and authorization requirements




  Exercise 3 - program preparation

perform PRECOMPILE
perform BIND
perform COMPILE
perform LINK-EDIT
perform RUN




  Program structure II

use DECLARE, OPEN, FETCH, and CLOSE CURSOR statements to handle select criteria that may return multiple rows in application programs
issue positioned UPDATE and DELETE statements
identify how scrollable cursors can be used (z/OS)




  Exercise 4 - program structure II

code DECLARE CURSOR statements in application programs to support retrieval of multi-row answer sets
code OPEN, FETCH, and CLOSE CURSOR statements
compare application enforcement of referential integrity with DB2 enforcement
ensure the WHENEVER statements have been coded properly
reinforce concepts presented in lecture that have been illustrated in the programming lab




  Recovery and locking concepts

define a unit of recovery
identify the basic locking strategies used by DB2




  Exercise 5 - restart

recognize the need for restarting a DB2 program
create a DB2 table and write code to support the restart




  Dynamic SQL introduction

describe the difference between static and dynamic SQL
list the types of dynamic statements
code dynamic SQL in a program




  Exercise 6 - dynamic SQL

code a FIXED-LIST dynamic SQL SELECT statement




  Managing test data

identify methods to insert data into a table
use the LOAD or IMPORT utility
identify the purpose of the RUNSTATS utility
identify the purpose of the REORG utility




  Exercise 7 - loading data

use the LOAD utility to add rows to a DB2 table




  Performance considerations

use programming techniques that enhance DB2 application performance by following general guidelines, using indexable predicates, and avoiding unnecessary sorts
identify the access paths available to DB2
list common causes of deadlocks and avoid such causes when possible
use the EXPLAIN tools as aids to develop applications that emphasize performance




  Exercise 8 - explain

populate explain tables from a single statement using SPUFI
populate explain tables from a program using BIND
determine if indexes are being used to satisfy SQL requirements
