When I run following Function with the following SETOF table...

it says:

NOTICE:  table "temp_production_product_operations" does not exist, skipping
CONTEXT:  SQL statement "drop table if exists 
temp_production_product_operations "
PL/pgSQL function "pb_report_temp_gerceklesme12" line 11 at execute 
statement

ERROR: set-valued function called in context that cannot accept a set
SQL state: 0A000
Context: PL/pgSQL function "pb_report_temp_gerceklesme12" line 56 at return 
next

Where is the error? I could not determined...



CREATE TABLE temp_temp_production_operations
( product_code character varying(25), product_name character varying(255), production_order bigint, stock_code character varying(25), operation_code bigint
) ;


===================================================
DROP FUNCTION pb_report_temp_gerceklesme12 ( character varying, character 
varying);

CREATE OR REPLACE FUNCTION pb_report_temp_gerceklesme12(character varying, 
character varying) RETURNS SETOF temp_temp_production_operations AS
$BODY$

DECLARE
tmp RECORD;
var_stock_code ALIAS FOR $1;
var_production_order ALIAS FOR $2 ;

BEGIN

-- drop temp table, if it exists (ignore exception if it doesn't) begin   execute 'drop table if exists temp_production_product_operations ' ;
   exception   when undefined_table then     null; -- do nothing end;


  EXECUTE 'create temp table temp_production_product_operations AS '|| ' SELECT stk.stock_code AS product_code, stk.stock_name AS product_name,  '|| ' NULL::integer AS production_order, pot.stock_code, pot.operation_code
