Kenny, thanks for the comment. The ‘date’ type was only added in SQL Server 2008. In all the prior versions you’ll need to do some mangling to be able to compare just the date portion.

What’s wrong with:
select cast(datetimefield as date) ?

Why go the hard way?
I tried it, and just casting to date type works, no floor, floats, .. involved..

SELECT * FROM TableName WHERE DATEPART(DY,Date) = DATEPART(DY,@date)

This is the best way by far:

DateAdd(day, datediff(day,0, MydateValue), 0)

Great article.
I tested with following example and it really works for me.

DECLARE @d1 SMALLDATETIME
DECLARE @d2 SMALLDATETIME

SET @d1 = (SELECT CAST(FLOOR(CAST( GETUTCDATE() AS float)) AS datetime))
SET @d2 = (SELECT CAST(FLOOR(CAST( GETDATE() AS float)) AS datetime))

–PRINT @d3
–PRINT @d4

IF(@d1 = @d2)
    PRINT 'both dates are equal'
ELSE
    PRINT 'no both dates are different'

Thanks dude.

If you compare two datetime fields in this way, the cast back to datetime should not be necessary. This saves some execution time.
