Eliminate Duplicates

Question of the Day

Default Objects in Clones

On SQL Server 2022, I do this:

USE model
GO
CREATE TABLE dbo.DBALog
(logdate DATETIME2(3), logmsg VARCHAR(2000))
GO
I then create a new database:
CREATE DATABASE INVENTORY
GO
I install a new database application in here with multiple tables, views, etc. I do not run any queries. I then decide to run this code:
DBCC CLONEDATABASE(INVENTORY, Inventory_clone);
GO
What happens?
