Summary of Predefined PL/SQL Exceptions An internal exception is raised automatically if your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. Also, it can use the pragma EXCEPTION_INIT to map specific error numbers returned by raise_application_error to exceptions of its own, as the following Pro*C example shows: EXEC SQL EXECUTE /* Execute For example, you might want to roll back a transaction in the current block, then log the error in an enclosing block. For example: EXCEPTION WHEN INVALID_NUMBER THEN INSERT INTO ... -- might raise DUP_VAL_ON_INDEX WHEN DUP_VAL_ON_INDEX THEN ... -- cannot catch the exception END; Branching to or from an Exception Handler A http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/errors.htm

The optional OTHERS exception handler, which is always the last handler in a block or subprogram, acts as the handler for all exceptions not named specifically. These conditions are not serious enough to produce an error and keep you from compiling a subprogram. If no handler is found, PL/SQL returns an unhandled exception error to the host environment. http://wiicentre.com/application-error/application-error-classnotfoundexception-oracle-forms-engine-main.html It's stored in a public Google Drive folder.chet February 14, 2014 at 9:09 AM Post a Comment Newer Post Older Post Home Subscribe to: Post Comments (Atom) Real World SQL and
