こんにちは、次のようなテーブルがあります。

                  Table Name: Emails
    ID        |CreatedDate             |finalStatus
    115173922 |2013-04-09 12:33:23.234 |DELIVERED
    115123432 |2013-04-09 08:21:23.234 |FAILED
    115143212 |2013-04-09 12:24:23.234 |DELIVERED
    115173922 |2013-04-09 05:05:23.234 |DELIVERED
    111233922 |2013-04-10 12:44:23.234 |PENDING
    115123912 |2013-04-10 12:05:23.234 |DELIVERED
    115173922 |2013-04-11 22:09:23.234 |DELIVERED
    111233922 |2013-04-11 13:05:23.234 |PENDING
    115123912 |2013-04-11 05:23:23.234 |DELIVERED

私がする必要があるのは、その月の 1 日あたりの DELIVERED、FAILED、および PENDING finalStatus の合計量を取得することです。次のような以前の回答で人々が提供したMySQLコードを変更しようとしました: SQL query for Calculating Total No. of Orders per Day? しかし、それを機能させることができませんでした。

これが私がこれまでに持っているコードです:

    SELECT DISTINCT  (CAST(CreatedDate as DATE)) as Date,

    (SELECT COUNT(finalStatus)
    FROM [Emails]
    WHERE finalStatus = 'DELIVERED') AS Delivered,

    (SELECT COUNT(finalStatus)
    FROM [Emails]
    WHERE finalStatus = 'FAILED') AS Failed,

    (SELECT COUNT(finalStatus)
    FROM [Emails]
    WHERE finalStatus = 'PENDING') AS Pending

    FROM [Emails]
    GROUP BY (CAST(CreatedDate as DATE))

誰かが私を助けることができれば、それは素晴らしいことです. 私はこれで数時間立ち往生しており、すぐに夢中になるかもしれません...

これはであるため、のみを使用してをSQL Server 2008にキャストすることを利用します。CREATEDDATEDATECAST()

SELECT CAST(E.CreatedDate AS DATE) DateCreated,
       COUNT(case when E.finalStatus = 'DELIVERED' then 1 end) as DELIVERED,
       COUNT(case when E.finalStatus = 'FAILED' then 1 end) as FAILED,
       COUNT(case when E.finalStatus = 'PENDING' then 1 end) as PENDING
FROM    TableName E
GROUP   BY CAST(E.CreatedDate AS DATE)

次のように月ごとに変更できます。

SELECT year(datestart), month(datestart)
finalStatus,
COUNT(finalStatus)
FROM [Emails]
GROUP BY year(datestart), month(datestart),finalStatus

このようなグループ化は、サブクエリよりもはるかに高速な方法です。

次のようなものが必要だと思います：

DATENAME

select CAST(CreatedDate as DATE),
       sum(case when E.finalStatus = 'DELIVERED' then 1 else 0 end) as DELIVERED,
       sum(case when E.finalStatus = 'FAILED' then 1 else 0 end) as FAILED,
       sum(case when E.finalStatus = 'PENDING' then 1 else 0 end) as PENDING
from Emails E
where DATENAME(MONTH,E.CreatedDate)='your month name'
group by CAST(E.CreatedDate as DATE)

取引のある日付のみを取得したい場合は、この回答を無視LUVしSkinny Pipes てください。

の 1 か月全体のすべての日付を取得することを考慮して、APRIL最初に の 1 か月全体のカレンダー テーブルを生成し、APRILそれをテーブルに結合する必要があります。このクエリは、再帰 CTE を使用してカレンダーを作成します。

WITH April_Calendar
AS
(
  SELECT CAST('20130401' as datetime) AS [date]
  UNION ALL
  SELECT DATEADD(dd, 1, [date])
  FROM   April_Calendar
  WHERE  DATEADD(dd, 1, [date]) <= '20130430'
)
SELECT  a.[Date] DateCreated,
        COUNT(case when E.finalStatus = 'DELIVERED' then 1 end) as DELIVERED,
        COUNT(case when E.finalStatus = 'FAILED' then 1 end) as FAILED,
        COUNT(case when E.finalStatus = 'PENDING' then 1 end) as PENDING
FROM    April_Calendar a
        LEFT JOIN Emails E
            ON a.[date] = CAST(E.CreatedDate AS DATE)
GROUP   BY a.[Date]

with daily_figures as
(
select 
 cast(CreatedDate as date) as CreatedDate,
 finalStatus,
 Count(*) as DayCount
From 
  EMails
Group 
  by cast(CreatedDate as date), FinalStatus
)
select * from daily_figures 
Where 
  datepart(month, CreatedDate) = 4 and
  datepart(year, CreatedDate) = 2013

必要な年をどのように提供するかは、アプリケーションの状況によって異なります。

これを試して

 SELECT DISTINCT  (CAST(CreatedDate as DATE)) as Date,

    (SELECT COUNT(finalStatus)
    FROM [Emails] E1
    WHERE finalStatus = 'DELIVERED'  AND 
    CAST(E1.CreatedDate as DATE) = CAST(E.CreatedDate as DATE)) AS Delivered,

    (SELECT COUNT(finalStatus)
    FROM [Emails] E2
    WHERE finalStatus = 'FAILED' AND 
     CAST(E2.CreatedDate as DATE) = CAST(E.CreatedDate as DATE)) AS Failed,

    (SELECT COUNT(finalStatus)
    FROM [Emails] E3
    WHERE finalStatus = 'PENDING' AND 
     CAST(E3.CreatedDate as DATE) = CAST(E.CreatedDate as DATE)) AS Pending

    FROM [Emails] E
    GROUP BY (CAST(CreatedDate as DATE))
