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)
