Count the number of comma’s in every record from a comma-separated value column in MySQL
Let us first create a −
mysql> create table DemoTable1510 -> ( -> Value varchar(50) -> ); Query OK, 0 rows affected (6.75 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1510 values('20,35');
Query OK, 1 row affected (0.57 sec)
mysql> insert into DemoTable1510 values('45,67,89');
Query OK, 1 row affected (0.99 sec)
mysql> insert into DemoTable1510 values('90,97,101,190');
Query OK, 1 row affected (1.15 sec)Display all records from the table using select −
mysql> select * from DemoTable1510;
This will produce the following output −
+---------------+ | Value | +---------------+ | 20,35 | | 45,67,89 | | 90,97,101,190 | +---------------+ 3 rows in set (0.00 sec)
Here is the query to count comma’s −
mysql> select length(Value) - length(replace(Value, ',', '')) as NumberOfComma from DemoTable1510;
This will produce the following output −
+---------------+ | NumberOfComma | +---------------+ | 1 | | 2 | | 3 | +---------------+ 3 rows in set (0.00 sec)
