Filter Stored Procedure Result (Informix)
Here is a illustration how works..
This was executed with dbaccess at Informix 11.50 FC9.
You can name your return parameters, but they are valid only when executed the procedure as procedure by self... not into select statement. There you need to name each column manually... check below.
