java之java.sql.SQLException: ResultSet is from UPDATE. No Data.

问题解释：java调用存储过程的时候，查询结果不能经过ResultSet来查询，须要经过CallableStatement来查询，

　　好比：

ResultSet rs = callableStatement.executeQuery(); while(rs.next()){ int empno = rs.getInt(1); String empname = rs.getString(2); System.out.println(empno); System.out.println(empname); }


//这种查询方式错误，报java.sql.SQLException: ResultSet is from UPDATE. No Data.


应该经过下面的方式：

　　int empno = callableStatement.getInt(1);　　String empname = callableStatement.getString(2);　　System.out.println(empno);　　System.out.println(empname);
