It already works this way. All string comparisons in MySQL are
case-insensitive, unless you have specifically marked a column as
having a case-sensitive collation, or are using a binary type instead
of a text type:
http://dev.mysql.com/doc/refman/5.1/en/string-type-overview.html
mysql> create table name_table ( name varchar(20) );
Query OK, 0 rows affected (0.07 sec)
mysql> insert into name_table values ('Joe'),('john'),('HARRY');
Query OK, 3 rows affected (0.09 sec)
Records: 3 Duplicates: 0 Warnings: 0
mysql> SELECT name FROM name_table WHERE name IN ('joe','john','harry');
+-------+
| name |
+-------+
| Joe |
| john |
| HARRY |
+-------+
3 rows in set (0.09 sec)
mysql> SELECT name FROM name_table WHERE name LIKE 'joe' OR name LIKE 'john' OR name
> LIKE 'harry' ;
+-------+
| name |
+-------+
| Joe |
| john |
| HARRY |
+-------+
3 rows in set (0.00 sec)
