can you search database for page values

I have taken over a Drupal 7 site which used to be on a different server and has now moved to ours. I have discovered that on lots of Pages, there are images which point to the wrong server name, the name being hard coded on the page. To save me having to load up each page to test (there are 1000’s of them), I thought I could search the database for the value I wish to change. I can see page information is stored in the node table but thats just the page title, created at, type etc. Which table is the text on the page stored in?
I have checked the settings.php file and the correct server name is in there. If I edit a page, I can see the html for the images that don’t show on the page point to a completely different server
