Sort character values from a column mixed with character and numbers in MySQL?
Let us first create a table −
mysql> create table DemoTable -> ( -> Code varchar(20) -> ); Query OK, 0 rows affected (0.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('J23');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('C13');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('A61');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('D56');
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select * from DemoTable;
This will produce the following output −
+------+ | Code | +------+ | J23 | | C13 | | A61 | | D56 | +------+ 4 rows in set (0.00 sec)
Here is the query to sort character values −
mysql> select * from DemoTable -> order by left(Code,1), -> cast(substr(Code, 2) as unsigned);
This will produce the following output −
+------+ | Code | +------+ | A61 | | C13 | | D56 | | J23 | +------+ 4 rows in set (0.05 sec)
