Need Help With An Insert/Update Query (PHP + MySQL) - ASAP

Hi there. I have a Dev environment on my hosting already set up and FTP Access ready to go. And, i'm working on a project right now - so I just want someone to do this part below for me while I focus on other parts. I just need someone to help me make a new query/function to insert Inventory Data into a simple table in my MySQL database. We already have an existing function (see [login to view URL] attached) that sort of does it, but it doesn't do it quite the way I need. The object / array loop is pretty simple (and I already made a table where you can insert/update this): [catalog_object_id] => DJ7DILGWOGEAYFROEGRZ34RT [catalog_object_type] => ITEM_VARIATION [state] => IN_STOCK [location_id] => L9QXQ2ZPP5T7A [quantity] => 0 [calculated_at] => 2022-09-23T22:54:59.658Z So I need to insert all those - but then, if I re-run the function, I need it to check this table and update the existing records (like where catalog_object_id, location_id already exist). Note: We could probably write a function that simply deletes the entire table and inserts the new results, but I'm not sure I want to do that - just in case we add manual inventory data in there (so that doesn't get deleted). Thanks!
