SQLCE: How to Count Datepart

Question

For a long time I am struggling with the following subject: I want to count datepart values. I use SQL Compact Edition 4.0 and have no idea on how to get the following:

select datepart(week, CreateDate) as Week, count(*) from tblOrders 
where CreateDate>'12 April 2010' and CreateDate<'25 June 2011'

This does not work obviously, but to give you an idea what I want to get as the result is: - 2 columns,

• one called "week" - that would be a week number
• in the second column - how many orders I had per week

Thanks in advance,

Pete

Answer 1

You'll need to add a Group By to make the query syntax correct.

select datepart(week, CreateDate) as Week, count(*) 
from tblOrders  where CreateDate>'12 April 2010' and CreateDate<'25 June 2011'
group by datepart(week, CreateDate)

Does that help?
