Re: PL/SQL exceptions handling help

I spent only a minute looking at this. So I may be wrong on this.

12   need_complete_refresh exception;
13   need_complete_refresh CONSTANT INTEGER := -12035;

need_complete_refresh is first declared as an exception, then that
declaration is over-written by declaring it as CONSTANT INTEGER.

Try removing line# 13 to see if it helps.

I've spent all morning R'ing the FMs and looking up examples and I still
can't get my PL/Sql to handle my user-defined exception.  Obviously I'm
missing something that is clear as a bell to all the people who post these
examples.  Any idea what it is?
