Hi Tom.

Ok. That was what I thougth too. But I just wanted to be sure I wasn't
missing anything.

Yeap, that was one of the answers I got. I thought there could be some
other way without modifying the function.

I was asking that because I received a lot of requests of being able to
get the number of rows affected by an executing function. And so I came
here because I didn't see anything in protocol which could be used.

Thanks for feedback Tom.
