What kind of string comparison, case-sensitive or not, can be performed by MySQL?

MySQL cannot perform a case-sensitive comparison when comparing characters. It can be illustrated with the following example from table ‘Employee’ having the following data −

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)

The result set of the following query shows that MySQL is not case sensitive when comparing characters.

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)
