I need to remove products via Cpanel File Manager

Where do I put these commands into CPanel File manager to search for and remove listings? The site has been taken down for the hosting company and the products must be removed this way.

DELETE FROM 'wpft_posts' WHERE post_title = 'stoneo' OR post_title like '%ahoy%'

SELECT * FROM `wpft_posts` WHERE post_title = 'stoneo' OR post_title like '%stoneo%'
