This is *not* a good idea. First, you must make it a selectable stored
procedure (using SUSPEND) and secondly, by selecting the return value, you
are extending the life of the transaction, when you really need to commit
it. This is a general rule for SPs - if you're doing DML, don't make it a
selectable procedure.

If an executable (i.e. DML) procedure has a RETURNS clause, then IBO
recognizes the return parameters and you can (1) get their metadata after
Prepare and (2) read their values after execution, via the Fields[] array.
