MySQL可以执行哪种字符串比较（区分大小写）？
比较字符时，MySQL无法执行区分大小写的比较。可以使用表'Employee'中的以下示例的以下示例进行说明-
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 (0.09 sec)
以下查询的结果集显示，比较字符时MySQL不区分大小写。
mysql> Select * from Employee WHERE Name IN ('gaurav','RAM');
+----+--------+--------+
| ID | Name | Salary |
+----+--------+--------+
| 1 | Gaurav | 50000 |
| 5 | Ram | 20000 |
+----+--------+--------+
2 rows in set (0.00 sec)
