Find rows with a match in a pipe delimited column with MySQL

To find a match, use regular expressions in MySQL. Let us first create a table −

mysql> create table DemoTable    -> (    -> Value varchar(60)    -> ); Query OK, 0 rows affected (0.48 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('8|56|78|45'); Query OK, 1 row affected (0.24 sec) mysql> insert into DemoTable values('9876'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values('98|8'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values('3|8|9'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('97|94'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values('103|104|110|8|97'); Query OK, 1 row affected (0.10 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable ;

This will produce the following output −

+------------------+ | Value            | +------------------+ | 8|56|78|45       | | 9876             | | 98|8             | | 3|8|9            | | 97|94            | | 103|104|110|8|97 | +------------------+ 6 rows in set (0.00 sec)

Here is the query to find rows with a match in a pipe-delimited column −

mysql> select *from DemoTable    -> where Value regexp '\|8\|';

This will produce the following output −

+------------------+ | Value            | +------------------+ | 3|8|9            | | 103|104|110|8|97 | +------------------+ 2 rows in set (0.00 sec)
