INSERT uses query_id to verify what fields are mentioned in the fields list of the INSERT command. However the check for that is made after the ON DUPLICATE KEY is processed. This causes all the fields mentioned in ON DUPLICATE KEY to be considered as mentioned in the fields list of INSERT. Moved the check up, right after processing the fields list.
