Now Terry Purcell and the optimizer crew came up with the PRUNED access plan in Db2 9: PRUNED. Db2 does not generate an access path for the query because the query is guaranteed to qualify zero rows, such as the case of an always-false WHERE clause. For example: WHERE 0 = 1. This happens when a “leg” of an SQL query cannot ever be true. For example, you may have a complex calculation that appears in many queries. Instead of including the formula in every query, you can create a scalar function that encapsulates the formula and uses it in each query.

Db2 stored procedures are supported using SQL Passthru. These procedures need to be developed within Db2 using the CREATE PROCEDURE command. The adapter supports stored procedures with IN, OUT, and INOUT parameters.

DB2 SQL - DML (Data Manipulation Language) - Part III In this part of the tutorial we will discuss about GROUP BY clause, HAVING clause and Functions in SQL.
