Does vanilla MySQL have a table name length limit?
(I've tested to 100 chrs on my modified MySQL - no limit so far.. I don't have vanilla MySQL accessible readily, though, but I wonder if my dynamically-created table schema will run on default MySQL)
Question: What happens if you go over 64 chrs on default MySQL? Can you test this please and paste MySQL error or results if any?
n.b. usage scenario where per user would never select another user's dataset.
