MySQL query to check if a string contains a word?

For this, you can use the LIKE operator along with CONCAT() function. Let us first create a table −

mysql> create table DemoTable
(
   Value text
);
Query OK, 0 rows affected (0.63 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('MySQL');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Is');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('Relational');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Database');
Query OK, 1 row affected (0.13 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+------------+
| Value      | 
+------------+
| MySQL      |
| Is         |
| Relational |
| Database   |
+------------+
4 rows in set (0.00 sec)

Following is the query to check if a string contains a word in a column −

Note − Below displays for a single word as a column value. The same works for an entire line or string, wherein you need to find only a word −

mysql> select Value from DemoTable where 'Relational' LIKE concat('%',Value,'%');

This will produce the following output −

+------------+
| Value      |
+------------+
| Relational |
+------------+
1 row in set (0.00 sec)
