@RobertCraigie I updated the tests and found here a bug in Prisma 😅
P.S. Look please at mypy (3.11) step why it doesn't pass.

Oh wow, thanks for reporting that!
The mypy failure is unrelated to your PR, I'll look into fixing it.

If you rebase against main, the mypy job should pass now.

I'll update docs, then wait for a response from the Prisma team, and if bug will be confirmed, then PR will be ready to final review 🎉

of course mysql doesn't even have a way to query that 🤦
I think it would be fine to just skip the tests for mysql if you haven't already.

Sorry, I didn't know that...
It marked with skipif.
