SourceTree ignore everything except one extension

[Hrvoje Velicki]

How to define in gitignore to ignore all except one file extension?

So I just want to track one file extensions.

I try something like this -> !*.sql 

but this not working.

Read here: https://git-scm.com/docs/gitignore

"An optional prefix "!" which negates the pattern; any matching file excluded by a previous pattern will become included again"

As said, you have to exclude everything first (with pattern '*') , then include some patterns again (your desired '!*.sql').
