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)
语法
Create or Replace View view_name AS Select_statements FROM table ORDER BY expression [ASC|DESC]
示例
mysql> Create or Replace View Info AS select ID, Name, Address , Subject FROM Student_info ORDER BY Name ASC; Query OK, 0 rows affected (0.11 sec) mysql> Select * from info; +------+---------+------------+------------+ | ID | Name | Address | Subject | +------+---------+------------+------------+ | 105 | Gaurav | Chandigarh | Literature | | 133 | Mohan | Delhi | Computers | | 130 | Ram | Jhansi | Computers | | 125 | Raman | Shimla | Computers | | 132 | Shyam | Chandigarh | Economics | | 101 | YashPal | Amritsar | History | +------+---------+------------+------------+ 6 rows in set (0.00 sec) mysql> Create or Replace View Info AS select ID, Name, Address , Subject FROM Student_info ORDER BY Name DESC; Query OK, 0 rows affected (0.10 sec) mysql> Select * from info; +------+---------+------------+------------+ | ID | Name | Address | Subject | +------+---------+------------+------------+ | 101 | YashPal | Amritsar | History | | 132 | Shyam | Chandigarh | Economics | | 125 | Raman | Shimla | Computers | | 130 | Ram | Jhansi | Computers | | 133 | Mohan | Delhi | Computers | | 105 | Gaurav | Chandigarh | Literature | +------+---------+------------+------------+ 6 rows in set (0.00 sec)
