Hi Larry: I am not sure if you are really "creating" SQL as much as this example implies, simply passing a value for substitution. If I am interpretting this correctly, you do not need a stored procedure (SP); a macro will work fine. A Macro can return rows where an SP can only return individual values in parameters. A macro to do this: CREATE MACRO My_Query (simno char(10)) AS (Select sim_mfr_no from valid_mfr where sim_mfr_no = :simno ;); Exec My_Query (' or USING simno char(10)) Exec My_Query (:simno); /* this technique is normally used when reading simno from disk file */ You are receiving an error on your SP because there is no "Prepare" command in stored procedural language(SPL). You simply put your SQL into a SP along with the appropriate SPL (you can do dynamic substitution in an SP like in a macro). Additionally, each select must reference a column in the WHERE that is defined as a UPI or USI to select only one row. If more than one row is expected, you must build a FOR/END FOR loop into the SP to process each row individually from SPOOL using a cursor. I hope this helps you accomplish your task. Mike
