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)
