MySQL ORDER BY with custom field value
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)
