Two ways through the first collection

The game taught SQL one keyword at a time: a checkpoint for WHERE, another for the AND after it, and the query traced out in grey for you to retype.

Guided

• SQL from nothing, one clause per checkpoint

• The query traced out, a detective at your shoulder

• 27 checkpoints across the five cases

Expert (or programmer)

• 13 checkpoints instead of 27: more deductions

• No dictated query, and nothing to retype

• One tour of the desk, then nothing speaks again

Also in this update

• The order of the columns is no longer part of the answer. SELECT at_time, kind, source and SELECT source, kind, at_time both pass.
