IMHO that request is completely bogus; if the procedure wants to tell
the client that, it's the procedure's responsibility to return the
number as a result. Doing what you ask (a) would arguably be a security
violation, and (b) the info would be impossible for the client to
interpret in any but the most trivial cases anyway. Consider for
instance a procedure that contains different queries in the THEN and
the ELSE arms of an IF, or contains loops executed a variable number
of times. Without access to the results of the control flow tests, the
client could not know which number means what.
