SQL courses and learning paths

Compare Complete SQL, Analytics, Engineering, and Interview paths by prerequisites, outcomes, modules, reviews, and projects.

This public page is designed to answer the learning question directly and then point to the interactive workspace only when practice is useful.

Compare Complete SQL, Analytics SQL, SQL for Engineers, and SQL Interview Practice by prerequisite level, depth, estimated effort range, outcomes, and included projects.

Each path points to ordered modules, cumulative reviews, representative original exercises, and the capstone or interview outputs it prepares.

The catalog keeps estimates as ranges and avoids fake guarantees about speed, jobs, rankings, certificates, or test scores.

The links below are canonical public resources. They render as normal anchors and do not require the product runtime.

Public pages explain concepts and show verified examples. The `/app` workspace adds the editor, PGlite worker, hidden variants, drafts, review scheduling, and mastery evidence.
