How to count specific comma separated values in a row retrieved from MySQL database?

To count comma-separated-values, use aggregate function COUNT(*) along with FIND_IN_SET(). Let us first create a table −

mysql> create table DemoTable (    Value varchar(100) ); Query OK, 0 rows affected (0.49 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('10,20,60,80'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('60,70,90'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('50,55,65,60'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('90,98,97'); 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 −

+-------------+ | Value       | +-------------+ | 10,20,60,80 | | 60,70,90    | | 50,55,65,60 | | 90,98,97    | +-------------+ 4 rows in set (0.00 sec)

Following is the query to count comma-separated values retrieved from the database −

mysql> select count(*) from DemoTable    where find_in_set('60',Value) > 0;

This will produce the following output −

+----------+ | count(*) | +----------+ |        3 | +----------+ 1 row in set (0.00 sec)
