过程或函数能返回或out静态游标吗？

CREATE OR REPLACE PACKAGE Types AS
  TYPE cursor_type IS REF CURSOR;
END Types;
/

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

在pl/sql中使用：
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
  v_cursor  Types.cursor_type;
  v_ename  emp.ename%TYPE;
  v_empno  emp.empno%TYPE;
  v_deptno  emp.deptno%TYPE;
BEGIN
  GetEmpRS (p_deptno    => 30,
            p_recordset => v_cursor);
           
  LOOP
    FETCH v_cursor
    INTO  v_ename, v_empno, v_deptno;
    EXIT WHEN v_cursor%NOTFOUND;
    DBMS_OUTPUT.PUT_LINE(v_ename || ' | ' || v_empno || ' | ' || v_deptno);
  END LOOP;
  CLOSE v_cursor;
END;
/

在java中使用：
import java.sql.*;
import oracle.jdbc.*;

public class TestResultSet  {
  public TestResultSet() {
    try {
      DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
      Connection conn = DriverManager.getConnection("jdbc:oracle:oci:@w2k1", "scott", "tiger");
      CallableStatement stmt = conn.prepareCall("BEGIN GetEmpRS(?, ?); END;");
      stmt.setInt(1, 30); // DEPTNO
      stmt.registerOutParameter(2, OracleTypes.CURSOR); //REF CURSOR
      stmt.execute();
      ResultSet rs = ((OracleCallableStatement)stmt).getCursor(2);
      while (rs.next()) {
        System.out.println(rs.getString("ename") + ":" + rs.getString("empno") + ":" + rs.getString("deptno"));
      }
      rs.close();
      rs = null;
      stmt.close();
      stmt = null;
      conn.close();
      conn = null;
    }
    catch (SQLException e) {
      System.out.println(e.getLocalizedMessage());
    }
  }

  public static void main (String[] args) {
