Restriction on exception

You can use exception only in an EXCEPTION_INIT pragma, RAISE statement, RAISE_APPLICATION_ERROR invocation, or exception handler.

Caution:

Oracle recommends against using a predefined exception name for exception. For details, see "Redeclared Predefined Exceptions". For a list of predefined exception names, see Table 11-3.
