How to sort an alphanumeric column in MySQL?
To sort an alphanumeric column, use LIKE operator along with SUBSTRING(). Let us first create a table −
mysql> create table DemoTable -> ( -> StudentId varchar(100) -> ); Query OK, 0 rows affected (1.54 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('S/TU/100');
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable values('S/TU/1000');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values('S/TU/10');
Query OK, 1 row affected (0.47 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+-----------+ | StudentId | +-----------+ | S/TU/100 | | S/TU/1000 | | S/TU/10 | +-----------+ 3 rows in set (0.00 sec)
Here is the query to sort an alphanumeric column in MySQL −
mysql> select StudentId from DemoTable where StudentId LIKE 'S%' order by substring(StudentId,1,9), substring(StudentId,10)*1;
Output
This will produce the following output −
+-----------+ | StudentId | +-----------+ | S/TU/10 | | S/TU/100 | | S/TU/1000 | +-----------+ 3 rows in set (0.00 sec)
