first of all sorry becuase these days i asked many questions.
and after that my new problem:
our company has a website that doesn't support sql(its hosting ofcourse)and forced me to upload my site under this hosting.at the other hand we have a server in our company that has valid ip.and my data base going to be a very huge data base.can i attach my data base to our server data base and upload my pages to the site?and it is a logic way or no?if it is possible and logic how should i do this.i know that shoul chand my server connection ip but i didn't find any address in my connection page

It is possible, but I wouldn't recommend it.

First of all, it may be problematic to set up. You need to open ports in the firewall (1433 if you're using Sql Server) on both ends of the connection.

Secondly, it may not perform very well. When your database is on the same machine as the web server, or at least in the same network, you have a high-speed, reliable connection. However, when you connect to your database over the internet, things may become slow or unreliable.

Finally, it may be a security risk to open Sql Server ports on your server and web site.

One way to fix this is to use a private (possibly VPN) line between you and the ISP. We have done that in the past and it solves a few of the problems.

Another alternative is to bring the site in, instead of with the ISP. Depending on the site, that may not be a workable solution though.
