Perform case insensitive SELECT using MySQL IN()?

Let us first create a table −

mysql> create table DemoTable1460
   -> (
   -> Name varchar(20)
   -> );
Query OK, 0 rows affected (0.91 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1460 values('Chris');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1460 values('David');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable1460 values('Bob');
Query OK, 1 row affected (0.52 sec)
mysql> insert into DemoTable1460 values('Robert');
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1460;

This will produce the following output −

+--------+
| Name   |
+--------+
| Chris  |
| David  |
| Bob    |
| Robert |
+--------+
4 rows in set (0.00 sec)

Following is the query to implement case insensitive SELECT using “IN” −

mysql> select * from DemoTable1460 where UPPER(Name) IN('CHRIS','BOB');

This will produce the following output −

+-------+
| Name  |
+-------+
| Chris |
| Bob   |
+-------+
2 rows in set (0.00 sec)
