In T-SQL:

BEGIN TRANSACTION

{query to update/delete records}

(If the query returned the expected amount of affected rows)

COMMIT TRANSACTION

(If the query did not return the expected amount of affected rows)

ROLLBACK TRANSACTION

Note: I’ve been told before that this will lock the affected table(s) until the changes made are committed or rolled back, but after looking it up it looks like it depends on a lot of minor details. Just be careful if you use it in production.
