Relative Dates

I need to create an SQL Statement that pulls data selected by a datetime
field. i want to be able to select dates and times relative to the time that
the query is run.
Can these date manipulations be done in the SQL statement?
Thanks
Have a look at DateDiff in BOL. Here is an example from SQL Server 2000 BOL:
USE pubs
GO
SELECT DATEDIFF(day, pubdate, getdate()) AS no_of_days
FROM titles
GO
GetDate() will allow you to compare to the time the query was run.

need to get all records that were created TODAY. then go on to records

|||Hi Mark,
something like this should do it:
SELECT cols FROM yourtable
where DATEDIFF(day, pubdate, getdate()) = 0
SELECT cols FROM yourtable
where DATEDIFF(day, pubdate, getdate()) <= n

Expanding on Paul's example, if you want to consider date and time:
DECLARE @.n int
SET @.n = 7
SELECT title
FROM titles
WHERE pubdate >= DATEADD(day, @.n * -1, GETDATE())
To consider date only:
DECLARE @.n int
SET @.n = 7
SELECT title
FROM titles
WHERE pubdate >= DATEADD(day, @.n * -1, DATEDIFF(day, 0, GETDATE())
Hope this helps.
