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)
