# Execute one bounded database write in Dev or Prod

> Owner-authorized INSERT, UPDATE or DELETE through the restricted runtime role, including ordinary upsert. Environment is mandatory. One direct statement and transaction, five-second timeout and at most 1000 directly affected rows; customer triggers and cascades may affect more rows. Rows are not returned. The durable Idempotency-Key receipt persists until project deletion. Same-key retries observe the original execution attempt; unknown outcomes never automatically execute again. Inspect target data before deliberately choosing a new key. Schema changes use GitHub migrations. Database compute is metered normally and existing credit grace and Stop budgets apply. Application row-level security policies remain effective for writes.
