Change link path in posts

I just moved my site to a new server/domain and I need to change a whole bunch of paths in links in my posts. It will be hard to do it manually but does anyone know the command to do it in MySQLDatabase?

Sometime like this:

Change: https://www.wordpress.com/sample.gif

To: https://www.mysite.com/sample.gif

Thanks, any help is greatly appreciated.
