如何在 ORDER BY 子句中使用 RAND() 函数来打乱 MySQL 行集？

mysql> Select * from employee; +----+--------+--------+ | ID | Name | Salary | +----+--------+--------+ | 1 | Gaurav | 50000 | | 2 | Rahul | 20000 | | 3 | Advik | 25000 | | 4 | Aarav | 65000 | | 5 | Ram | 20000 | | 6 | Mohan | 30000 | | 7 | Aryan | NULL | | 8 | Vinay | NULL | +----+--------+--------+ 8 rows in set (0.00 sec)

现在，下面的查询将使用 ORDER BT RAND() 来打乱结果集中的行集 -

mysql> Select * from Employee ORDER BY RAND();
+----+--------+--------+
| ID | Name   | Salary |
+----+--------+--------+
| 4  | Aarav  | 65000  |
| 1  | Gaurav | 50000  |
| 3  | Advik  | 25000  |
| 7  | Aryan  | NULL   |
| 6  | Mohan  | 30000  |
| 8  | Vinay  | NULL   |
| 5  | Ram    | 20000  |
| 2  | Rahul  | 20000  |
+----+--------+--------+
8 rows in set (0.00 sec)
