The "id" column for the "log_clients" table isn't an identity (auto-increment) column. Instead, it uses a natural key: the conversion of the dotted IP address to its numeric equivalent. The MySQL function INET_ATON can be used to remove the non-numeric characters from ip_client so the value can be inserted into log_clients.id. Use an INSERT-SELECT statement to populate your "log_clients" table. (Hint: populate log_clients.id as INET_ATON(ip_client) ). Be sure to populate both columns of the log_clients table with one SQL statement.

my attempt: insert into log_clients (id , client_ip) select log_clients.id as inet_aton,ip_client from log_all;
