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)
