How to check if a specific country code exists in a cell with MySQL?
For specific value, use FIND_IN_SET(). Let us first create a −
mysql> create table DemoTable1439 -> ( -> CountryId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> CountryCode varchar(20) -> ); Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1439(CountryCode) values('1022_US,7894_UK');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1439(CountryCode) values('6567_AUS,7894_UK');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1439(CountryCode) values('6567_AUS');
Query OK, 1 row affected (0.09 sec)Display all records from the table using select −
mysql> select * from DemoTable1439;
This will produce the following output −
+-----------+------------------+ | CountryId | CountryCode | +-----------+------------------+ | 1 | 1022_US,7894_UK | | 2 | 6567_AUS,7894_UK | | 3 | 6567_AUS | +-----------+------------------+ 3 rows in set (0.00 sec)
Following is the query to check if country code exists in a cell −
mysql> select * from DemoTable1439
-> where find_in_set('6567_AUS',CountryCode) > 0;This will produce the following output −
+-----------+------------------+ | CountryId | CountryCode | +-----------+------------------+ | 2 | 6567_AUS,7894_UK | | 3 | 6567_AUS | +-----------+------------------+ 2 rows in set (0.00 sec)
