But the basics of almost everything are approachable. The basics of Prolog, Haskell [1], Basic, etc, are all approachable. I learned programming with GW Basic, back when I was a kid; it's learnable, but I wouldn't enjoy building complex software with it.
SQL itself is a complex beast. Approachable in parts and with training, like many complex tools.
We were also taught prolog, asm and (weirdly) pascal. We didn't manage to actually produce anything interesting in any of those. The Access CRUD apps and the little VB6 games were the only working software that came out of that two year class.
