Check if value exists in a comma separated list in MySQL?

To check if value exists in a comma separated list, you can use FIND_IN_SET() function.

The syntax is as follows

SELECT *FROM yourTablename WHERE FIND_IN_SET(‘yourValue’,yourColumnName) > 0;

Let us first create a table. The query to create a table is as follows

mysql> create table existInCommaSeparatedList - > ( - > Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, - > Name varchar(200) - > ); Query OK, 0 rows affected (0.68 sec)

Now you can insert some records in the table using insert command.

The query is as follows

mysql> insert into existInCommaSeparatedList(Name) values('John,Carol,Sam,Larry,Bob,David'); Query OK, 1 row affected (0.35 sec) mysql> insert into existInCommaSeparatedList(Name) values('Maxwell,Chris,James'); Query OK, 1 row affected (0.14 sec) mysql> insert into existInCommaSeparatedList(Name) values('Robert,Ramit'); Query OK, 1 row affected (0.34 sec)

Display all records from the table using select statement.

The query is as follows

mysql> select *from existInCommaSeparatedList;

The following is the output

+----+--------------------------------+ | Id | Name | +----+--------------------------------+ | 1 | John,Carol,Sam,Larry,Bob,David | | 2 | Maxwell,Chris,James | | 3 | Robert,Ramit | +----+--------------------------------+ 3 rows in set (0.00 sec)

Here is the query to check if value exists in a comma separated list. We are checking for the field with comma separated text “Robert”

mysql> SELECT *FROM existInCommaSeparatedList WHERE FIND_IN_SET('Robert',Name) > 0;

The following is the output

+----+--------------+ | Id | Name | +----+--------------+ | 3 | Robert,Ramit | +----+--------------+ 1 row in set (0.00 sec)
