What if I call another function I wrote myself that returns an INT, but I do not care about the INT? Maybe that
functiondoes the insert and returns the number of inserted rows.
I can think of all kinds of reasons this might be the case; whether they are good or bad approaches is immaterial:
sometimesyou work with what you have.
I am find with PERFORM to determine when a query's results should be discarded. I just think it needs to cover a few
morecases.
Best,
