How to sort by arbitrary keywords in MySQL?

For this, use the ORDER BY FIELD() ASC. Let us first create a table −

mysql> create table DemoTable(Title varchar(100));
Query OK, 0 rows affected (0.56 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Java');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('C');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Python');
Query OK, 1 row affected (0.63 sec)
mysql> insert into DemoTable values('MongoDB');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+---------+
| Title   |
+---------+
| Java    |
| C       |
| Python  |
| MongoDB |
+---------+
4 rows in set (0.00 sec)

Following is the query to sort by arbitrary keywords −

mysql> select *from DemoTable order by FIELD(Title,'MongoDB,C,Python,Java') ASC;

This will produce the following output −

+---------+
| Title   |
+---------+
| Java    |
| C       |
| Python  |
| MongoDB |
+---------+
4 rows in set (0.00 sec)
