Re: Create a table from a stored procedure result set with dynamic columns

dynamically create the sql select statement as a string. Then use PREPARE
and OPEN to run the statement.

CREATE or replace PROCEDURE test_Select(
in inCucode char(6)
)
LANGUAGE SQL
DYNAMIC RESULT SETS 1
BEGIN
declare vSqlCode decimal(5,0) ;
declare sqlCode int DEFAULT 0 ;
DECLARE QT CHAR(1) DEFAULT '''' ;
declare vStmt char(5000) default ' ' ;

DECLARE C1 CURSOR FOR s1 ;

set vStmt =
' select a.orhordnum ordnum, a.orhcust cucode ' ||
' from dwhpf30c a ' ||
' where ( ? = '' '' or ? = a.orhcust) ' ||
' order by a.orhordnum ' ||
' fetch first 50 rows only ' ;

prepare s1
from vStmt ;

OPEN C1
using inCucode, inCucode ;

SET RESULT SETS WITH RETURN TO CLIENT CURSOR C1 ;

END

Hi,



I have an SQL stored procedure that successfully creates a result set
(pivot
data) which returns dynamic columns.

How can I create a table based on the result set where the columns can
vary?



Thank you.
