9-8. Associating Error Numbers with Exceptions That Have No Name
Problem
You want to associate an error number to those errors that do not have predefined names.
Solution
Make use of PRAGMA EXCEPTION_INIT to tell the compiler to associate an Oracle error number with an exception name. This will allow the use of an easy-to-identify name rather than an obscure error number when working with the exception. The example in this recipe shows how an error number can be associated with an exception name and how the exception can later be raised.
