In SQL Source Control v3.4, there is now an option to link your database to a working folder. On the commit tab, there is an option to “Save” the database changes to the working folder. This scripts the objects and static data to files. You can then use your own version control system’s tool to commit the changes alongside other changes that also exist in this area. The folder for the database needs to be separate from the other files, so it might be nice to have a top level project folder with a folder for the application and another folder for the database below. Therefore, to commit both application and database changes, you would commit from the higher project folder. You can also have more folders for documentation and other things that you want to source control.
