To set custom field value, use FIND_IN_SET(). Let us first create a table −
mysql> create table DemoTable677( UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, UserStatus text ); Query OK, 0 rows affected (1.07 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable677(UserStatus) values('BUSY'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable677(UserStatus) values('AT WORK'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable677(UserStatus) values('OFFLINE'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable677(UserStatus) values('BLOCKED'); Query OK, 1 row affected (0.17 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable677;
This will produce the following output −
+--------+------------+ | UserId | UserStatus | +--------+------------+ | 1 | BUSY | | 2 | AT WORK | | 3 | OFFLINE | | 4 | BLOCKED | +--------+------------+ 4 rows in set (0.00 sec)
Following is the query to ORDER BY with custom field value −
mysql> select *from DemoTable677 ORDER BY FIND_IN_SET(UserStatus, 'BLOCKED,AT WORK,OFFLINE,BUSY');
This will produce the following output −
+--------+------------+ | UserId | UserStatus | +--------+------------+ | 4 | BLOCKED | | 2 | AT WORK | | 3 | OFFLINE | | 1 | BUSY | +--------+------------+ 4 rows in set (0.03 sec)
