Creating the Oracle Tables
These examples use tables that are defined in the Oracle Scott/Tiger schema. By default, the Oracle Scott/Tiger schema is included with a standard Oracle installation. However, if this schema does not exist, you can use the SQL commands file in {OracleHome}\rdbms\admin\scott.sql to create the tables and indexes used by these examples.
Creating the Oracle Package and Package Body
These examples require the following PL/SQL package and package body. You must create these on your server to use the examples.
Create the following Oracle package on the Oracle server.
CREATE OR REPLACE PACKAGE CURSPKG AS
TYPE T_CURSOR IS REF CURSOR;
PROCEDURE OPEN_ONE_CURSOR (N_EMPNO IN NUMBER,
IO_CURSOR IN OUT T_CURSOR);
PROCEDURE OPEN_TWO_CURSORS (EMPCURSOR OUT T_CURSOR,
DEPTCURSOR OUT T_CURSOR);
END CURSPKG;
/
Create the following Oracle package body on the Oracle server.
CREATE OR REPLACE PACKAGE BODY CURSPKG AS
PROCEDURE OPEN_ONE_CURSOR (N_EMPNO IN NUMBER,
IO_CURSOR IN OUT T_CURSOR)
IS
V_CURSOR T_CURSOR;
BEGIN
IF N_EMPNO0
THEN
OPEN V_CURSOR FOR
SELECT EMP.EMPNO, EMP.ENAME, DEPT.DEPTNO, DEPT.DNAME
FROM EMP, DEPT
WHERE EMP.DEPTNO = DEPT.DEPTNO
AND EMP.EMPNO = N_EMPNO;
ELSE
OPEN V_CURSOR FOR
SELECT EMP.EMPNO, EMP.ENAME, DEPT.DEPTNO, DEPT.DNAME
FROM EMP, DEPT
WHERE EMP.DEPTNO = DEPT.DEPTNO;
END IF;
IO_CURSOR := V_CURSOR;
END OPEN_ONE_CURSOR;
PROCEDURE OPEN_TWO_CURSORS (EMPCURSOR OUT T_CURSOR,
DEPTCURSOR OUT T_CURSOR)
IS
V_CURSOR1 T_CURSOR;
V_CURSOR2 T_CURSOR;
BEGIN
OPEN V_CURSOR1 FOR SELECT * FROM EMP;
OPEN V_CURSOR2 FOR SELECT * FROM DEPT;
EMPCURSOR:= V_CURSOR1;
DEPTCURSOR := V_CURSOR2;
END OPEN_TWO_CURSORS;
END CURSPKG;

This Microsoft® Visual Basic® example executes a PL/SQL stored procedure that returns two REF CURSOR parameters, and fills a DataSet with the rows that are returned.
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim cmd As New OracleCommand()

cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New OracleParameter("EMPCURSOR", OracleType.Cursor)).Direction = ParameterDirection.Output
cmd.Parameters.Add(New OracleParameter("DEPTCURSOR", OracleType.Cursor)).Direction = ParameterDirection.Output
