Can we use IN() to search between comma separated values within one field?

Instead of IN(), use FIND_IN_SET to search between comma separated values within one field. Let us first create a table −

mysql> create table DemoTable
   -> (
   -> ListOfValues text
   -> );
Query OK, 0 rows affected (0.56 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('10|20|30|40|50|60|100');
Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-----------------------+
| ListOfValues          |
+-----------------------+
| 10|20|30|40|50|60|100 |
+-----------------------+
1 row in set (0.00 sec)

Following is the query to search between comma separated values within one field −

mysql> select FIND_IN_SET(100, replace(ListOfValues,'|',',')) from DemoTable;

This will produce the following output −

+-------------------------------------------------+
| FIND_IN_SET(100, replace(ListOfValues,'|',',')) |
+-------------------------------------------------+
|                                               7 |
+-------------------------------------------------+
1 row in set (0.04 sec)
