關於在ORACLE的存儲過程中返回結果集和JAVA取得結果的試驗例子

先創建包和包體
CREATE OR REPLACE PACKAGE PKG_TEST
IS
     TYPE T_CURSOR IS REF CURSOR;
   PROCEDURE pro_test(cur OUT T_CURSOR);
   FUNCTION fun_test return    T_CURSOR;
END;

包體
CREATE OR REPLACE PACKAGE BODY PKG_TEST
AS
   PROCEDURE pro_test
     (cur OUT   T_CURSOR)
       IS
         V_CURSOR T_CURSOR;
       BEGIN
                 insert into tmp_table values(111);
         insert into tmp_table values(222);
         OPEN V_CURSOR FOR
             select * from tmp_table;
            cur := V_CURSOR;
            commit;
       END;
     function fun_test return T_CURSOR
     IS
        V_CURSOR T_CURSOR;
       BEGIN
         OPEN V_CURSOR FOR
             select * from tmp_table;
          return   V_CURSOR;
       END;
END;

Java代碼片段
    Connection conn = ....
    conn.setAutoCommit(false);
    CallableStatement proc = conn.prepareCall("{call ? := pkg_test.fun_test}");
    proc.registerOutParameter(1, OracleTypes.CURSOR);
    proc.execute();
    ResultSet rs = (ResultSet) proc.getObject(1);   
    while(rs.next())
    {
             //取得結
