You can use FIND_IN_SET to structure some data in a database for easier retrieval. Let us first create a table −
mysql> create table DemoTable ( CountryName SET('US','UK','AUS') ); Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('US'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable values('UK'); Query OK, 1 row affected (0.09 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------------+ | CountryName | +-------------+ | US | | UK | +-------------+ 2 rows in set (0.00 sec)
Following is the query to fetch a value −
mysql> select *from DemoTable where find_in_set('UK',CountryName) > 0;
This will produce the following output −
+-------------+ | CountryName | +-------------+ | UK | +-------------+ 1 row in set (0.00 sec)
