我们可以使用 MySQL ORDER BY 子句对结果集中的记录进行排序。 。为了理解带有视图的 GROUP BY 子句，我们使用具有以下数据的基表“Student_info”创建一个名为“Info”的视图 -
mysql> Select * from Student_info;
+------+---------+------------+------------+
| id | Name | Address | Subject |
+------+---------+------------+------------+
| 101 | YashPal | Amritsar | History |
| 105 | Gaurav | Chandigarh | Literature |
| 125 | Raman | Shimla | Computers |
| 130 | Ram | Jhansi | Computers |
| 132 | Shyam | Chandigarh | Economics |
| 133 | Mohan | Delhi | Computers |
+------+---------+------------+------------+
6 rows in set (0.00 sec)
