It didn't "involve the handling of multiple rows of output data".
It involved no output data. The select returned an empty result-set.
If you are suggesting that by reading that explanation you understand
that you will get an AV when you use a select that returns an empty
result-set I agree with you: the help really helps.
The problem is I didn't understand that. It must be my poor
understanding of english language.
