academy sqlmap essentials case:10

I’m a bit stuck on Case 10 for the sqlmap essentials course. It says “What’s the contents of table flag10? (Case #10)” I’ve been banging my head on the wall for a bit. I’m able to perform a scan against the page with an case10.php?id=1 ending, but it says there are no vulnerabilities with the parameter. I’ve tried various techniques, but they haven’t gotten me anywhere. Is the cc column a hash of some other column? I didn’t see any logic for hashing in the response. I could use some hints.

Im so stuck there, did u get the flag??
