Run my databse site on local computer

Hi ,

I am trying to install my database site on my local computer but when I try to run on local server , the browser connect the server of my web hoster.

My procedure is :1) I make database cakup of my site, 2) installa the local server and wamp, 3) I run the wordpress on local server without problem.
so, when I run the database of my site to local server, I can not connect locally. It seems that the databe bring something that makes me connect to webhost..

Is it possible to help me solve the problem, because it is imortant for me run locally the site, so I can make tests..thank you
