关于在ORACLE的存储过程中返回结果集和JAVA取得结果的试验例子

先创建包和包体

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;

包体

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代码片段

    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())
    {

             //取得结果
     }
