Result Sets with Different Databases

Result Sets with Different Databases

Configure stored procedures to return result sets using different syntax based on the database type.


An Oracle stored function returns results with a cursor:
create or replace function sp_ListEmp return types.cursortype as l_cursor types.cursorType; begin open l_cursor for select ename, empno from emp order by ename; return l_cursor; end;
Oracle also accepts cursors as input parameters. You cannot configure cursors as input parameters with the SQL transformation.

Microsoft SQL Server

A Microsoft SQL Server stored procedure returns a result set stored procedure with a select statement in the procedure body or with the return type explicitly declared as a table.
Create PROCEDURE InOut( @inout varchar(100) OUT ) AS BEGIN set @inout = concat(@inout,'__') select * from mytable; END


An IBM DB2 stored procedure can return a resultset with an open cursor. The number of result sets it returns are declared in the RESULT SET clause. The stored procedure opens a cursor and returns it. The below example returns 2 open cursors.
CREATE PROCEDURE TESTMULTIRS (IN i_cmacct CHARACTER(5)) RESULT SETS 2 LANGUAGE SQL BEGIN DECLARE csnum INTEGER; --Declare serial cursors to consume less resources --You do not need a rollable cursor. DECLARE getDeptNo CHAR(50); --Be careful with the estimated length. DECLARE getDeptName CHAR(200); DECLARE c1 CURSOR WITH RETURN FOR s1; SET getDeptNo = 'SELECT DEPTNO FROM DEPT'; SET getDeptName = 'SELECT DEPTNAME FROM DEPT'; PREPARE s1 FROM getDeptNo; OPEN c1; END;


A Sybase stored procedure returns a result set stored procedure with a select statement in the procedure body or with the return type explicitly declared as a table.
CREATE PROCEDURE FETCHEMPINFO ( @p_State VARCHAR(5), @e_id INT OUTPUT, @e_name VARCHAR(50) OUTPUT ) AS BEGIN SET NOCOUNT ON SELECT EMP_ID, NAME FROM EMP WHERE STATE = @p_State ORDER BY EMP_ID SET NOCOUNT OFF SELECT @e_id AS EMP_ID, @e_name AS NAME RETURN END GO --Configure the following variables to execute the procedure. DECLARE @p_State VARCHAR(5) DECLARE @EMPID int DECLARE @EMPNAME varchar(50) SET @p_State = 'CA' exec FETCHEMPINFO @p_State, @e_id = @EMPID, @e_name = @EMPNAME GO
