Seems like the SQL Server 2022 fails due to a problem with datatypes. Was the CI DB backends changed?

Could be something changed in the workflow that starts the instance (not our workflow).

I just check our local MS SQL Server Version 15.00.4375 and it provides the expected datatypes. A guess is that the CI version uses DATETIME2 instead of DATETIME - the latter is sufficient for our purpose.

Could also be an update to SQL Server 2022

Approved, but support of SQL Server 2022 should be added in a future PR.
