This tutorial teaches you how to create,
test, and deploy a DB2 SQL stored procedure. Stored procedures can
help improve application performance and reduce database access traffic.
All database access must go across the network, which, in some cases,
can result in poor performance. For each SQL statement, a database
application must initiate a separate communication with DB2. To improve
application performance, you can create stored procedures that run
on your database server. A client application can then simply call
the stored procedures to obtain results of the SQL statements that
are contained in the procedure. Because the stored procedure runs
the SQL statement on the server for you, database performance is improved.
In addition, stored procedures can help to centralize business logic.
If you make changes to a stored procedure, the changes are immediately
available to all client applications that use it.
Learning objectives
When
you complete the exercises, you will know how to do the following
tasks:
