ORDERBY word in MySQL?

MySQLMySQLi Database

To order by word in MySQL, you need to use ORDER BY FIELD(). Let us first create a table −

mysql> create table DemoTable
(
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentFirstName varchar(20),
   StudentFavouriteSubject varchar(100)
);
Query OK, 0 rows affected (0.52 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(StudentFirstName,StudentFavouriteSubject) values('Larry','Java');
Query OK, 1 row affected (0.12 sec)

mysql> insert into DemoTable(StudentFirstName,StudentFavouriteSubject) values('Sam','C');
Query OK, 1 row affected (0.11 sec)

mysql> insert into DemoTable(StudentFirstName,StudentFavouriteSubject) values('Bob','MongoDB');
Query OK, 1 row affected (0.17 sec)

mysql> insert into DemoTable(StudentFirstName,StudentFavouriteSubject) values('David','MySQL');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement;

mysql> select *from DemoTable;

This will produce the following output −

+-----------+------------------+-------------------------+
| StudentId | StudentFirstName | StudentFavouriteSubject |
+-----------+------------------+-------------------------+
|         1 | Larry            | Java                    |
|         2 | Sam              | C                       |
|         3 | Bob              | MongoDB                 |
|         4 | David            | MySQL                   |
+-----------+------------------+-------------------------+
4 rows in set (0.00 sec)

Following is the query to ORDER BY word in MySQL −

mysql> select *from DemoTable
ORDER BY FIELD(`StudentFavouriteSubject`, 'MongoDB','MySQL','Java','C');

This will produce the following output −

+-----------+------------------+-------------------------+
| StudentId | StudentFirstName | StudentFavouriteSubject |
+-----------+------------------+-------------------------+
|         3 | Bob              | MongoDB                 |
|         4 | David            | MySQL                   |
|         1 | Larry            | Java                    |
|         2 | Sam              | C                       |
+-----------+------------------+-------------------------+
4 rows in set (0.03 sec)
