Exception Handler

An exception handler processes a raised exception. Exception handlers appear in the exception-handling parts of anonymous blocks, subprograms, triggers, and packages.

Semantics

exception

Name of either a predefined exception (see Table 11-3) or a user-defined exception (see "Exception Declaration").

If PL/SQL raises a specified exception, then the associated statements run.

OTHERS

Specifies all exceptions not explicitly specified in the exception-handling part of the block. If PL/SQL raises such an exception, then the associated statements run.

Note:

Oracle recommends that the last statement in the OTHERS exception handler be either RAISE or an invocation of the RAISE_APPLICATION_ERROR procedure.

If you do not follow this practice, and PL/SQL warnings are enabled, you get PLW-06009.

In the exception-handling part of a block, the WHEN OTHERS exception handler is optional. It can appear only once, as the last exception handler in the exception-handling part of the block.
