How to sort domain names in MySQL?
To sort domain names, use the ORDER BY SUBSTRING_INDEX(). Let us first create a table −
mysql> create table DemoTable670(DomainName text); Query OK, 0 rows affected (0.77 sec)
Insert some records in the table using insert command. Here, we are inserting domain names −
mysql> insert into DemoTable670 values('www.facebook.com');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable670 values('www.google.com');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable670 values('www.amazon.com');
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement −
mysql> select *from DemoTable670;
This will produce the following output −
+------------------+ | DomainName | +------------------+ | www.facebook.com | | www.google.com | | www.amazon.com | +------------------+ 3 rows in set (0.00 sec)
Following is the query to sort domains in MySQL −
mysql> select *from DemoTable670 order by SUBSTRING_INDEX(DomainName, '.', -2),SUBSTRING_INDEX(DomainName, '.', 2);
This will produce the following output −
+------------------+ | DomainName | +------------------+ | www.amazon.com | | www.facebook.com | | www.google.com | +------------------+ 3 rows in set (0.00 sec)
