How to select date without time in SQL

Question

When I select date in SQL it is returned as 2011-02-25 21:17:33.933. But I need only the Date part, that is 2011-02-25. How can I do this?

Answer 1

The fastest is datediff, e.g.

select dateadd(d, datediff(d,0, [datecolumn]), 0), other..
from tbl

But if you only need to use the value, then you can skip the dateadd, e.g.

select ...
WHERE somedate <= datediff(d, 0, getdate())

where the expression datediff(d, 0, getdate()) is sufficient to return today's date without time portion.
