QueryForge
Read a SQL query, predict the exact result set — which rows, in which order — then run it to check. QueryForge shows you a table and a query, and asks you to think through WHERE, ORDER BY, DISTINCT and LIMIT before you press run (the habit that catches a bug before it ships). Every wrong option is a real misreading the engine actually produces. No timer, no score to chase; on-device, no account. Ages 15–18.
#3b5ba9 Distributed-narrative cast
Meet the cast
QueryForge is SELECT … FROM … WHERE … ORDER BY … LIMIT pulled apart into the moves each clause makes — the crew IS the query. Filo filters, Sorel sorts, Sole de-duplicates, Capp caps; mentor Delia keeps the one habit that separates a developer from a guesser: read the query and PREDICT the result before you run it. 15–18, text-forward (R-OLDER-TEEN-DN-ADAPTED) — illustrated portraits/chapters/audio are N/A for the older-teen band, not a follow-on.
Filo
WHERE — keeps only the rows that pass the test and drops the rest (a filter is a test applied to every row)
Sorel
ORDER BY — arranges the rows in order; DESC flips it high→low (the sort never changes which rows, only their order)
Sole
DISTINCT — keeps one of each kind and folds the repeats away (de-duplication runs after projection)
Capp
LIMIT — takes just the first N, after WHERE/ORDER BY/DISTINCT have all done their work
Delia
(Mentor) — read the query and predict the result set BEFORE you run it; that habit catches a bug before it ships.
