SQL Server : get max/min possible date without magic numbers
I know that the SQL Server date datatype is defined to have a range of 0001-01-01 to 9999-12-31. Is there any way to obtain those values using T-SQL without the use of magic numbers (e.g. without something like declare @MaxDate date = '12/31/9999')?
