Oh.. I did what AN-Net said, but i cant restore the database via cpanel cuz the database is too big..

how do l restore the database without the cpanel. thnx

Do you have shell access?

If so: Upload the file, mysql -uusername -ppassword database < sqlfile.sql

Whats shell access? and how to use it?

You don't have shell access - if you had it you would know for sure.
Sorry, seems you're out of luck.
You could only ask your webhost to give you shell access

I dunno, where do you use it? or is it like what a telnet did?

You can access a shell through telnet, although it is very insecure.
I'd rather use SSH2 if possible.

how do you use it? and how do you get it connect to your server.
