I always used to strip off the time by converting to a character
string. I only learned the DATEADD/DATEDIFF approach recently from
reading the SQL Server newsgroups. I am told it is far more
efficient, but I am still trying to decide if it is readable. But I
have had to create some real messes with character strings and
DATEPART and such too.
I still haven't really accepted the simple date arithmatic: SET
@datetime2 = @datetime1 + 2 from your example. I know it works in
days, but I like the explicit unit DAY in DATEADD. I don't even
bother to use the abbreviations in DATEADD, DATEPART or DATENAME any
more, as I find the full word more explicit.
