I almost always have trouble remembering which option is for use with a non-empty folder of “here’s a bunch of files that I want to dump into the repo to start with”, vs. “here’s an empty folder where I want to pull down the contents of an existing repo”. Fortunately, Tortoise yells at you if you try to do the latter — which is
Export— into a non-empty folder. So we want to
Import. Assuming you have a folder where all your SQL scripts live already, right-clicky and say “Tortoise SVN .. Import.”
Check it out. The only concern I have is that this source control is just local source control. That’s very helpful in situations where you accidentally mess something up, but my preference is to put my code in the same source control system the developers are using. And if the developers aren’t using source control, get that institution in place as soon as possible because that’s begging for trouble.
