Thanks Andreas but is there no alternative?
I'm porting from an INFORMIX database which allows the return of more than one value from a stored procedure without having to use in/out parameters. The procedure is called from several places across the system and will be time consuming to change all instances to include the new out parameters. To be able to return more than one parameter will be of great help to me, if it's possible.
Many Thanks
Atif
