The UPDATE you wish you could take back

A repeatable workflow for checking the target, running the write, and retaining a recovery path.

01 · FIELD GUIDE

Preview the same condition

Start with a SELECT that uses the exact condition planned for the write. Check the count and sample values, then narrow the predicate if anything looks surprising.

SELECT id, customer_id, status
FROM orders
WHERE id = 3001
  AND status = 'pending';
Confirm the intended order and its current state before changing it.

Make the write explicit

Keep the WHERE clause specific. Rowset Studio's default policies block UPDATE and DELETE without an effective WHERE clause, but a valid condition can still match the wrong rows. Personal policies add further limits for statements, objects, result counts, duration and write windows.

SET status = 'shipped'
WHERE id = 3001
  AND status = 'pending';
The predicate checks both the identifier and the expected previous status.

Choose the right recovery tool

In manual commit mode, inspect the result before Commit. Rollback can cancel an open transaction. For eligible UPDATE or DELETE changes, optional row backups provide a separate Restore path even after Commit.

For sensitive data, inspect the generated Restore script and the current records before applying it. The backup represents the values before your write; later edits require extra care.
