Steve *is* using EXECUTE, so that doesn't seem to be the answer. I'm
wondering about datatype mismatches myself --- the function form is
forcing the parameter to be char(9), which is not a constraint imposed
in the written-out query. There are lots of other possibilities
though. It would be hard to say much without a self-contained example
to try.
He's using EXECUTE ... USING. Does that plan with the used parameter?
