The developer in question has been publicly humiliated. And since he lurks on this list...humiliated again here. =)

Steve,

Why aren't the developers using table.column%type ?

OK after spending a good chunk of each day for three days playing with tkprof, and pondering the possibilities of why a query withing a PL/SQL function would perform SO differently than when it is run from sqlplus, I finally actually read the PL/SQL code. The data type of one of the cursor variables was mismatched. As a result, the proper index was unused, resulting in either a full table scan(if I used the developer's +0 code) or
a range scan on a poor index. Thanks again for all the helpful hints, and guidance.
