High-signal Habits
Keep one tab per objective, commit changes in small steps, and verify affected row counts before and after writes.
Use explicit transaction boundaries when testing uncertain update logic.
Pre-run Query Checklist
Check target schema, filter predicates, join keys, and limit clauses before execution in sensitive environments.
BEGIN;
-- Run and validate your update
-- SELECT checks here
ROLLBACK; -- Replace with COMMIT only when validated
