Sort a column in descending order after placing argument in MySQL IN()?
For this, use FIELD() function with DESC. Let us first create a table −
mysql> create table DemoTable -> ( -> Number int -> ); Query OK, 0 rows affected (0.57 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(10); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(20); Query OK, 1 row affected (0.27 sec) mysql> insert into DemoTable values(30); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(40); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values(50); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+--------+ | Number | +--------+ | 10 | | 20 | | 30 | | 40 | | 50 | +--------+ 5 rows in set (0.00 sec)
Following is the query to sort a column in descending order after placing argument in MySQL IN() −
mysql> select *from DemoTable where Number IN (40,50,20,30,10) ORDER BY FIELD(Number, 40,50,20,30,10) DESC;
Output
This will produce the following output −
+--------+ | Number | +--------+ | 10 | | 30 | | 20 | | 50 | | 40 | +--------+ 5 rows in set (0.03 sec)
