I've asked a question about SQL, not asking for a piece of code per se, but more of a general advice.
I hesitated between Stack Overflow and Super User, tried a search on the topic, found thousands of questions on SQL and VBA (some with piece of code) on Super User, and it seemed a nice fit. Four people voted it to migrate it in minutes, without explanation.
How is it that questions on VBA, which is a programming language OK here, but not on SQL, which is not a programming language per se? What's the line between Stack Overflow and Super User?
