I am using a time field in my where clause that is returning the proper results..except for April and May below is the query?

declare @sdate date
declare @edate date

set  @sdate  = dateadd(YY,-1,GETDATE())
set  @edate  = GETDATE()

select @sdate, @edate

select datepart(m,recorddate),SUM(qty_invoiced)
from   inv_item
where item = 'f7000356'
and    tax_date between @sdate and @edate
group by  datepart(m,recorddate)



-------------------------------------------------------------------------------------

We need some examples of "proper results." What does your data look like, what are the expected results and what are the actual results?

Results from first query: (4 and 5 are incorrect)
1      411.00000000
2      107.00000000
3      360.00000000
4      668.00000000
5      164.00000000
6      836.00000000
7      422.00000000
8      30.00000000
10      81.00000000
11      432.00000000
12      180.00000000
Expected Results of 4 and 5  (There are 2 carring over from 4 to 5)
4      742.00000000
5      90.00000000

The two carring over both have the date 2012-04-30 00:00:00.000, they are both added to MAY resulting in the 164 total.

It was created on 05/01/2012 tax_date was back dated to 04/30/2012, but i would think they results should still be returned properly from the first query also.

Is it an option to change your query to include times, just to make sure you're picking up the right values ?

You shouldn't ever assume values if you're looking for exact results, specify exactly what you want:

select datepart(m,tax_date),SUM(qty_invoiced)
from   inv_item
where item = 'f7000356'
and tax_date between '04/01/2012 00:00:00.000' and '04/30/2012 23:59:59.999'
group by  datepart(m,tax_date)

The problem was the group by.  It is now running properly I am very sorry.  Thank you for the help.  The first query had the group by on record date.
