I think I broke my SQLite

I was following along with this tutorial:

When I went to view the page in browser I got this error:

Didn’t know how to get rid of this error so I clicked on ‘Move. to Trash’. I don’t get the error anymore but my data does not show on my test page either.

How can I recover that file and get rid of the error? (I still have the file in my trash bin)
