SQL-每周报告，为期7天（星期日至星期六）

Question

我创建了以下查询，从周六和周日开始每隔7天重复一次。该报告将每七天运行一次。但是，在我们的SFTP文件夹（入站）报告中收到文件的那天，我面临的问题应该是缺少Null = 0的条目。使此自动化过程的主要目标是每个星期日都将执行每七天星期日 示例：

SELECT SubmitterID,SubmitterName,convert(varchar(15), DateReceived, 101) DateReceived,sum(ClaimCount) as TotalCount
FROM FalloutClaimReport
WHERE DateReceived BETWEEN '2019-06-01' AND '2019-06-07'
--ORDER BY COUNT(submitterID) DESC;
GROUP BY submitterid, SubmitterName, convert(varchar(15), DateReceived, 101)

DECLARE @StartDate AS DATETIME
DECLARE @EndDate AS DATETIME
DECLARE @CurrentDate AS DATETIME

SET @StartDate = '2019-06-01' --AND '2019-06-10'
SET @StartDate = '2019-06-07'
SET @EndDate = GETDATE()
SET @CurrentDate = @StartDate

我不确定您在寻找什么，但是我认为一般的方法是您试图获取一周的数据。

日期计算

让我们从一些查询开始（这些查询假定美国安装为默认日期为星期一。

SELECT
    DATEADD(WEEK, -1, CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, CAST(GETDATE() AS date)), -1) AS date)) AS TheLastSundayOfTheFullWeek
,   DATEADD(WEEK, -1, CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, CAST(GETDATE() AS date)), +5) AS date)) AS TheLastSaturdayOfTheFullWeek
,   CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, CAST(GETDATE() AS date)), -1) AS date) AS SundayOfTheCurrentWeek
,   CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, CAST(GETDATE() AS date)), +5) AS date) AS SaturdayOfTheCurrentWeek;

这些查询生成以下日期

TheLastSundayOfTheFullWeek TheLastSaturdayOfTheFullWeek SundayOfTheCurrentWeek SaturdayOfTheCurrentWeek
2019-06-30                 2019-07-06                   2019-07-07             2019-07-13

最后一整周的运行时间为6/30至7/06。当前一周将定义为7/7至7/13。

根据您需要的星期定义，选择合适的两列。

应对未知事物

在这种情况下，我构建了一个虚拟表，其中包含报告应具有的所有预期日期（或元素）。然后，我用它来驱动到实际数据表的连接。由于我们不知道给定日期会找到任何行，因此我将这些表与LEFT JOIN连接起来

SELECT
    FCR.SubmitterID
,   FCR.SubmitterName
,   CONVERT(varchar(15), ED.DateReceived, 101) AS DateReceived
,   SUM(FCR.ClaimCount) AS TotalCount
FROM
    (
        -- This logic builds out a list of all the dates that must exist on the report
        -- I used the logic for TheLastSundayOfTheFullWeek
        SELECT
            DATEADD(DAY, D.DayOffset, DATEADD(WEEK, -1, CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, CAST(GETDATE() AS date)), -1) AS date))) AS DateReceived
        FROM
        (
            -- Generate a series of 7 numbers from 0 t 6
            SELECT TOP 7
                -1 + ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS rn
            FROM
                sys.all_columns AS AC 
        ) D(DayOffset)
    ) AS ED
    LEFT OUTER JOIN
        dbo.FalloutClaimReport AS FCR
        ON FCR.DateReceived = ED.DateReceived
GROUP BY
    CONVERT(varchar(15), ED.DateReceived, 101)
,   FCR.SubmitterID
,   FCR.SubmitterName;

生成的结果集如下

我们在30号或5号没有数据，但查询中仍然有记录。如果您需要在其中使用默认值，请使用ISNULL / COALESCE调用包装该列。

奥黛丽，

我会提出两种可能的解决方案。假设您指的是SRS，SSRS。...

1）我将您的SSIS作业设置为每7天通过SQL代理运行一次。它将调用存储过程（SP），然后运行该存储过程并将其写入表中……当调用该SP时，它将运行：

SELECT 
SubmitterID,
SubmitterName,
convert(varchar(15), DateReceived, 101) DateReceived,
sum(ClaimCount) as TotalCount
FROM FalloutClaimReport
WHERE cast(DateReceived as date) BETWEEN dateadd(d,-7,cast(getdate() as date)) AND dateadd(d,-1,cast(getdate() as date))

GROUP BY 
submitterid,
SubmitterName,
convert(varchar(15), DateReceived, 101)

2）如果您决定采用SSRS路由，则应进行报告订阅，该报告订阅会自动发送给您需要的用户，该用户调用上面的存储过程，并将需要的信息发送给需要它的任何人。 （上面的代码应该足以假设它正在选择所需的内容）
