3 ms·Ask HN: Are there any good resources to practice SQL?1 points by avyfain 13y agoI need to prepare for an analytics interview. Does anyone know of a good resource to practice SQL querying/database design stuff online?LogicX 13y agoJackdb.com - I recently used it to play with their sample db and teach basic SQL to my MIS class. Worked out rather well.avyfain 13y agoThanks! This is pretty cool, but I was looking for something with guided exercises more than just a sandbox. Any other ideas?
