Question

如何在sql server 2008中获得上个月销售和本月销售我的表结构是：

DailyDispatchID int Unchecked 
Name    varchar(50) Checked
Qty int Checked
Month   varchar(50) Checked

我试过这个：

SELECT *
FROM   (SELECT Name,
               Gas,
               Qty,
               Month
        FROM   DailyDispatch) AS s
       PIVOT (Sum(QTY)
             FOR [month] IN(aug,
                            sep)) AS P

我正在获得输出，但它仅从8月和9月开始。它应该自动生成本月和之前的销售。如何解决这个问题。

SELECT Name,
       Gas,
       Qty,
       [Month]
FROM   DailyDispatch
WHERE  [Month] IN (SELECT CASE
                            WHEN Month(Getdate()) = 1 THEN 'jan'
                            WHEN Month(Getdate()) = 2 THEN 'feb'
                            WHEN Month(Getdate()) = 3 THEN 'mar'
                            WHEN Month(Getdate()) = 4 THEN 'apr'
                            WHEN Month(Getdate()) = 5 THEN 'may'
                            WHEN Month(Getdate()) = 6 THEN 'jun'
                            WHEN Month(Getdate()) = 7 THEN 'jul'
                            WHEN Month(Getdate()) = 8 THEN 'aug'
                            WHEN Month(Getdate()) = 9 THEN 'sep'
                            WHEN Month(Getdate()) = 10 THEN 'oct'
                            WHEN Month(Getdate()) = 11 THEN 'nov'
                            WHEN Month(Getdate()) = 12 THEN 'dec'
                          END [month]
                   UNION ALL
                   SELECT CASE
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 1 THEN 'jan'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 2 THEN 'feb'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 3 THEN 'mar'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 4 THEN 'apr'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 5 THEN 'may'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 6 THEN 'jun'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 7 THEN 'jul'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 8 THEN 'aug'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 9 THEN 'sep'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 10 THEN 'oct'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 11 THEN 'nov'
                            WHEN Month(Dateadd(mm, -1, Getdate())) = 12 THEN 'dec'
                          END [month])
