Narayan writes "Hi,

I need SQL query to get the last week's data

I am using the following condition

select convert(datetime, convert(nvarchar,datepart(yyyy,getdate()))
+ '-' + convert(nvarchar,datepart(mm,getdate()))+ '-' + convert(nvarchar,datepart(dd,getdate()-7)))

but if current system date is 3 and if i do -7 it throws up error. How do I get last week date by using current sys date

Regards,
Narayan"

[code]
select [Begin of Last Week] = dateadd(week, datediff(week, 0, getdate()), -7),
[Begin of This Week] = dateadd(week, datediff(week, 0, getdate()), 0)

SELECT . . .
FROM . . .
WHERE datecol >= dateadd(week, datediff(week, 0, getdate()), -7)
AND datecol < dateadd(week, datediff(week, 0, getdate()), 0)
[/code]

Please define what you consider a week is.

Monday-Sunday?
Sunday-Saturday?

What happens over new year? When is new year?
