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

[Steve Richter <stephenrichter@xxxxxxxxx>]

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
