The PL/SQL Feature Cost Evaluator (known commonly as the Piffkey) has determined that it costs Oracle Corporation $221 to declare a new exception in the PL/SQL language. Therefore, every effort should be made to reuse previously-defined exceptions whenever possible. Please notify all members of the PL/SQL Development Team to "Think Before Adding" or TBA, and we can all contribute to Larry's mighty vision of a $1B savings this year!
