as helen says - but just a note on logic, you are assuming the presence of
id just because it's being passed to the procedure.
A better logic would be to select for id and see if the record exists before
trying to update it. It may not exist, but updating where id does not exist
will be silent. YOu wont know if anything at all has happened.
