Convert the column to a case-sensitive collation in MySQL?

For this, you can use COLLATE. Following is the syntax −

select *from yourTableName where yourColumnName LIKE yourValue COLLATE utf8_bin;

Let us first create a table −

mysql> create table DemoTable
   (
   LastName varchar(100)
   );
Query OK, 0 rows affected (0.51 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Brown');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('BROWN');
Query OK, 1 row affected (0.29 sec)
mysql> insert into DemoTable values('brown');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('BRoWN');
Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

+----------+
| LastName |
+----------+
| Brown    |
| BROWN    |
| brown    |
| BRoWN    |
+----------+
4 rows in set (0.00 sec)

Following is the query for COLLATE −

mysql> select *from DemoTable where LastName LIKE 'BROWN' COLLATE utf8_bin;

Output

+----------+
| LastName |
+----------+
| BROWN    |
+----------+
1 row in set (0.00 sec)
