There are not real queries: ItemDate is a datetime column
SELECT * FROM Items WHERE ItemDate > CURRENT_TIMESTAMP
SELECT * FROM Items WHERE ItemDate > getdate()
Also, if you have a DateTime field, can you set it's default to be CURRENT_TIMESTAMP? Or should you use getdate() as it's default value?
I am understand the difference between the datetime column type and the timestamp column type, but I was wondering about the CURRENT_TIMESTAMP variable and if you can use it the same as getdate() in calculations etc.
