This is a question about the SQL Server 2019 trial version.

1. I understand that the trial version lasts 180 days. What happens after it expires? Can’t I use it at all?? I searched on the internet and it said that it will shut down within 1 hour when you turn it on. Is this correct?

2. I am using SQL server 2019 Enterprise Evaluation Edition, but the expiration date is not long. What I have is a standard license. Can I enter the standard key?
