MySQL query to copy IP address from varchar column to integer in the same table?

For this, you can use INET_ATON(). Let us first create a −

mysql> create table DemoTable1404    -> (    -> IpAddress varchar(40)    -> ); Query OK, 0 rows affected (1.02 sec)

Insert some records in the table using insert −

mysql> insert into DemoTable1404 values('192.168.120.0'); Query OK, 1 row affected (0.43 sec) mysql> insert into DemoTable1404 values('192.168.120.20'); Query OK, 1 row affected (0.60 sec) mysql> insert into DemoTable1404 values('224.0.0.0'); Query OK, 1 row affected (0.42 sec)

Display all records from the table using select −

mysql> select * from DemoTable1404;

This will produce the following output −

+----------------+ | IpAddress      | +----------------+ | 192.168.120.0  | | 192.168.120.20 | | 224.0.0.0      | +----------------+ 3 rows in set (0.00 sec)

Following is the query to copy IP address from varchar column to integer in the same −

mysql> select inet_aton(IpAddress) from DemoTable1404;

This will produce the following output −

+----------------------+ | inet_aton(IpAddress) | +----------------------+ |           3232266240 | |           3232266260 | |           3758096384 | +----------------------+ 3 rows in set (0.00 sec)

No, let us prove that the conversion was successful or not −

mysql> select inet_ntoa('3232266240');

This will produce the following output −

+-------------------------+ | inet_ntoa('3232266240') | +-------------------------+ | 192.168.120.0           | +-------------------------+ 1 row in set (0.27 sec)
