Select all records if it contains specific number in MySQL?

For this, use concat() along with LIKE. Following is the syntax −

select *from yourTableName where concat(',', yourColumnName, ',') like '%,yourValue,%';

Let us create a table −

mysql> create table demo49
−> (
−> id varchar(20)
−> ,
−> first_name varchar(20)
−> );
Query OK, 0 rows affected (1.45 sec)

Insert some records into the table with the help of insert command −

mysql> insert into demo49 values('4,5,6',
−> 'Adam');
Query OK, 1 row affected (0.20 sec)

mysql> insert into demo49 values('5,3,2','Mike');
Query OK, 1 row affected (0.19 sec)

mysql> insert into demo49 values('3,4,9','Bob');
Query OK, 1 row affected (0.14 sec)

Display records from the table using select statement −

mysql> select *from demo49;

This will produce the following output −

+-------+------------+
| id    | first_name |
+-------+------------+
| 4,5,6 | Adam       |
| 5,3,2 | Mike       |
| 3,4,9 | Bob        |
+-------+------------+
3 rows in set (0.00 sec)

Following is the query to select all records if it contains specific number −

mysql> select *from demo49 where concat(',', id, ',') like '%,4,%';

This will produce the following output −

+-------+------------+
| id    | first_name |
+-------+------------+
| 4,5,6 | Adam       |
| 3,4,9 | Bob        |
+-------+------------+
2 rows in set (0.00 sec)
