Hi Orvin,
Thank you for reaching out to our API support team.
Since you mentioned that you are using a 3rd party connector which is make.com to query google ads into SQL server, to be honest with you the make.com is out of our scope support. Moving forward to your concern about "historical data," historical metrics cannot generate campaign total cost per day. To learn more about this, you can visit this link. On the other hand, what we can do is filter the date by using segments.date and metrics.cost_micros to generate the campaign total cost per day. To further help you, you can make use of the Query Builder to help you construct and validate queries.
If you have additional questions that is specific to Google Ads API, feel free to send those over to our team and we would be happy to assist you further.
Best,
