Implement case sensitivity in MySQL SELECT statements
SELECT is by default case-insensitive. For case-sensitive implementation, the BINARY operator is used. Following is the syntax :
select *from yourTableName where BINARY yourColumnName=yourValue;
Let us first create a table −
mysql> create table DemoTable ( Name varchar(40) ); Query OK, 0 rows affected (0.74 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('CHRIS');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('chris');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('CHris');
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+ | Name | +-------+ | Chris | | CHRIS | | chris | | CHris | +-------+ 4 rows in set (0.00 sec)
Following is the query for case-sensitive select −
mysql> select *from DemoTable where BINARY Name='Chris';
This will produce the following output −
+-------+ | Name | +-------+ | Chris | +-------+ 1 row in set (0.04 sec)
