The table where your URL is saved is wp_options. You should do an update on the columns that use the URL for your site:
UPDATE TABLE wp_options SET option_value = "new domain" WHERE option_name = "siteurl"
UPDATE TABLE wp_options SET option_value = "new domain" WHERE option_name = "home"
I might be missing some value, but whenever you do this find/replace process again, you can notice the values and tables that should be updated and add them to this script.
