Order by numeric value from string records separated by numbers like CSE 15, CSE 11, etc.?
Let us first create a table −
mysql> create table DemoTable1969 ( BranchCode varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1969 values('CSE 101');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1969 values('CSE 11');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1969 values('CSE 15');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1969 values('CSE 6');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1969 values('CSE 201');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1969 values('CSE 110');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1969;
This will produce the following output −
+------------+ | BranchCode | +------------+ | CSE 101 | | CSE 11 | | CSE 15 | | CSE 6 | | CSE 201 | | CSE 110 | +------------+ 6 rows in set (0.00 sec)
Here is the query to order by numeric value from string records separated by numbers −
mysql> select * from DemoTable1969
order by CAST(SUBSTRING(BranchCode,LOCATE(' ',BranchCode)+1) AS SIGNED) DESC;This will produce the following output −
+------------+ | BranchCode | +------------+ | CSE 201 | | CSE 110 | | CSE 101 | | CSE 15 | | CSE 11 | | CSE 6 | +------------+ 6 rows in set (0.00 sec)
