Close the Fractured Loom

The Lockward seal waits. Five floors of queries stand behind you — one wrong result set and the gate stays shut.

Clear the previous chamber to unlock this one. You can still preview the briefing.

Briefing

Final weave: active weavers who logged a shift, totals in WITH, rank by woven tension — every prior thread pulled tight.

Objective

Return weaver name, total, and RANK() OVER (ORDER BY total DESC) as standing for active weavers with EXISTS in shifts and totals from WITH, ordered by standing.

Hint

WITH totals, JOIN weavers + totals, EXISTS shifts, active = 1, RANK() on total, ORDER BY standing.

Results appear here after you run a query. Correct rows alone are not enough — the Warden must seal your loot.

Warden

I am the Warden. Ask for a hint, paste a failing query, or request a review — I won't hand you the full answer.
