DateTime2 vs DateTime in SQL Server

Question

Which one:

• datetime
• datetime2

is the recommended way to store date and time in SQL Server 2008+?

I\'m aware of differ

Answer 1

Select ValidUntil + 1
from Documents

The above SQL won't work with a DateTime2 field. It returns and error "Operand type clash: datetime2 is incompatible with int"

Adding 1 to get the next day is something developers have been doing with dates for years. Now Microsoft have a super new datetime2 field that cannot handle this simple functionality.

"Let's use this new type that is worse than the old one", I don't think so!
