Question of the Day

Adding Defaults

I have a table, called dbo.logger, in SQL Server 2022. I decide to add two new columns to this table with this code.

ALTER TABLE dbo.logger ADD CreateDate DATETIME CONSTRAINT dfGetDate DEFAULT GETDATE()
GO
ALTER TABLE dbo.logger ADD ModifyDate DATETIME DEFAULT dfGetDate
GO
What happens when I run these two batches?
