mysql从另一列复制数据

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 ?

Answer 1

简单的查询将为您完成此操作

update table set ip_start_long = INET_ATON(ip_start);
