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)
