Ref Cursors

Using Ref Cursors

The example below uses a ref cursor to return a subset of the records in the EMP table.
The following procedure opens a query using a SYS_REFCURSOR output parameter. Notice the cursor is not closed in the procedure. It is up to the calling code to manage the cursor once it has been opened.

CREATE OR REPLACE
PROCEDURE get_emp_rs (p_deptno    IN  emp.deptno%TYPE,
                      p_recordset OUT SYS_REFCURSOR) AS 
BEGIN 
  OPEN p_recordset FOR
    SELECT ename,
           empno,
           deptno
    FROM   emp
    WHERE  deptno = p_deptno
    ORDER BY ename;
END GetEmpRS;
