Sort only numbers from alphanumeric string in MySQL?

To sort only numbers from alphanumeric string, use ORDER BY RIGHT(). Let us first create a table −

mysql> create table DemoTable1948    (    StudentCode varchar(20)    ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1948 values('121John_567'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1948 values('Adam_101'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1948 values('Bob_563'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1948 values('Sam_346'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1948;

This will produce the following output −

+-------------+ | StudentCode | +-------------+ | 121John_567 | | Adam_101    | | Bob_563     | | Sam_346     | +-------------+ 4 rows in set (0.00 sec)

Here is the query to sort only numbers from alphanumeric string in MySQL −

mysql> select * from DemoTable1948    order by RIGHT(StudentCode,3);

This will produce the following output −

+-------------+ | StudentCode | +-------------+ | Adam_101    | | Sam_346     | | Bob_563     | | 121John_567 | +-------------+ 4 rows in set (0.00 sec)
