mysql copy data from another column

Question

I have 2 columns, ip_start, ip_start_long

ip_start        |  ip_start_long
------------------------------------
0.255.255.255   |  16777215

I need to convert ip_start (INET_ATON) and copy update to ip_start_long for all rows (1 million rows)

How can I do it in php or phpmyadmin ?

简单的查询将为您完成此操作
