Interactive path — a structured SQL syllabus (14 parts); each part loads a self-contained on-demand lesson (novice-friendly depth, Oracle + TPC-H lab SQL, quick-check questions you can send to Guided practice). Interview prep uses topic cards. Guided practice answers any question. Always verify SQL before you run it.
