SQL Server：将日期时间与GETDATE（）进行比较

Question

I have a stored procedure that should fetch all records with a date equal to the current date or in the future. The dates are saved in column targetDate and formatted as datetime. My corresponding WHERE clause is the following:

WHERE A.targetDate >= GETDATE()

In general my stored procedure works fine, my only problem is if the targetDate equals the current date as all dates are saved as follows, ie with the time set to zeros:

2014-02-22 00:00:00.000

How do I have to change my WHERE clause so that it only considers the date but ignores the time saved with it so that I get any records with the current date even if the time is already passed ?

Many thanks for any help with this, Tim.

Answer 1

Change to:

WHERE A.targetDate >= cast(GETDATE() as date)

Edit - because targetdate also contains time, yes, format both like this:

WHERE cast(A.targetDate as date) >= cast(GETDATE() as date)

Edit - given comments re: performance, may want to try:

WHERE a.targetdate >= cast(cast(getdate() as date) as datetime)

Last edit should give you the same result and take advantage of any indexes on targetdate

Answer 2

The following should give you the current date with no time:

SELECT DATEADD(dd,0,DATEDIFF(dd,0,GETDATE()))

This should be your final line:

WHERE A.targetDate >= DATEADD(dd,0, ATEDIFF(dd,0,GETDATE()))
