WHENEVER

---

Defines action to be taken for errors and exception conditions.

Usage

Embedded.

Description

The action taken in the event of a condition arising during execution of an SQL statement is governed by the most recently issued WHENEVER statement. There are three different types of conditions: NOT FOUND, SQLERROR and SQLWARNING. See Return Status and Conditions for a description of the different condition types.

The action taken is as follows:

• CONTINUE

  Program execution continues at the next sequential statement of the source program.

• GOTO

  Program execution continues at the source code statement identified by host-label, where host-label is a program label in a program written according to the host language.

Restrictions

None.

Notes

If a condition in an SQL statement is not covered by an explicit WHENEVER statement issued earlier in the host program code, CONTINUE will be assumed.

Example

      ...
       GOTO 1025
       EXEC SQL WHENEVER SQLERROR GOTO 1600
 1025  CONTINUE
       EXEC SQL DELETE FROM MYTABLE
      ...
