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

問題解釋：java調用存儲過程的時候，查詢結果不能經過ResultSet來查詢，須要經過CallableStatement來查詢，

　　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); }


//這種查詢方式錯誤，報java.sql.SQLException: ResultSet is from UPDATE. No Data.


應該經過下面的方式：

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