I have data that has 2 columns, a status and a date.

is it possible to build the following report in SQL and if so how would I do it

                  Today         Yesterday           Week             Month
StatusA
StatusB

So I would want a total sent today from statusA and B then yesterdays everything this week and finally everything this month (last 7 and 30 days)

So, count of all StatusAs for today, count of all from yesterday, etc?

Assuming my assumption above is correct...

DECLARE @StDate datetime = 
    (SELECT MIN(x.Dt)
    FROM
        (SELECT CONVERT(date, DATEADD(day, 1 - DATEPART(WEEKDAY, GETDATE()), GETDATE())) AS Dt
        UNION
        SELECT DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0) AS Dt) x)

SELECT s.[Status],
    SUM(CASE 
        WHEN DATEDIFF(day, s.[Date], GETDATE()) = 0 THEN 1
        ELSE 0 END) AS [Today],
    SUM(CASE 
        WHEN DATEDIFF(day, s.[Date], GETDATE()) = 1 THEN 1
        ELSE 0 END) AS [Yesterday],
    SUM(CASE 
        WHEN DATEDIFF(week, s.[Date], GETDATE()) = 0 THEN 1
        ELSE 0 END) AS [ThisWeek],
    SUM(CASE 
        WHEN DATEDIFF(month, s.[Date], GETDATE()) = 0 THEN 1
        ELSE 0 END) AS [ThisMonth]
FROM [SomeTable] s
WHERE s.[Date] >= @StDate
GROUP BY s.[Status]

That works a treat, just a quick question before I close it off, if I wanted to use a different date field for 2 different statuses is this possible? From what I know I would have to create 2 different views with the different date field but just thought I would throw it out there.

For example 2 status  "Sent Out" and "Returned"  with 2 dates "date Sent Out" and "Date Returned"

Sounds to me that that approach could be extended to additional date columns...
