Syntax error Sort values that contain letters and symbols in custom order with MySQL

Sort values that contain letters and symbols in custom order with MySQL

For custom order, use ORDER BY FIELD(). Let us first create a table −

mysql> create table DemoTable
(
   Title varchar(100)
);
Query OK, 0 rows affected (0.62 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Java_1+');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('MySQL_23+');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('MongoDB++');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('C++_23');
Query OK, 1 row affected (0.13 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-----------+
| Title     |
+-----------+
| Java_1+   |
| MySQL_23+ |
| MongoDB++ |
| C++_23    |
+-----------+
4 rows in set (0.00 sec)

Following is the query to sort values that contain letters and symbols in a custom order −

mysql> select *from DemoTable order by field(Title,'MySQL_23+','C++_23','Java_1+','MongoDB++');

This will produce the following output −

+-----------+
| Title     |
+-----------+
| MySQL_23+ |
| C++_23    |
| Java_1+   |
| MongoDB++ |
+-----------+
4 rows in set (0.00 sec)
