Re: ROWNUM

Any select into results in two fetches!
The first to trap no_data_found
the second one to trap too many rows,as a select into always returns 1 row. So using 'and rownum = 1' is a method to suppress the too many rows message, hence to suppress data problems.
In my current project I'm working with inherited code where this construct is sprinkled all of the place.
Of course, disaster already did strike!
Fortunately the death penalty doesn't exist here any more.

Just to warn you: DON"T USE IT!!!
