How to check if any of the strings in a column contains a specific string in MySQL?
For this, use CONCAT() along with LIKE operator. Let us first create a table −
mysql> create table DemoTable ( Name varchar(40) ); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.33 sec)
mysql> insert into DemoTable values('Adam');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('Bob');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values('Johnson');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+---------+ | Name | +---------+ | John | | Adam | | Bob | | Johnson | | David | +---------+ 5 rows in set (0.00 sec)
Following is the query to check if any of the strings in a column contains a specific string −
mysql> select *from DemoTable where Name like "%Joh%" OR "Joh" LIKE CONCAT("%", Name, "%");This will produce the following output −
+---------+ | Name | +---------+ | John | | Johnson | +---------+ 2 rows in set (0.00 sec)
