我应该在月份月变化报告中使用哪些表达式？ （SSRS）

Question

我的报告设置如下。我正在使用每月的行组（我打算在最终草案中隐形）来比较本月的第一个月和上个月的第一个，依此类推。

当我运行它时，它看起来像这样

哪个是完美的。然而我需要的是在每天填写空白行，底行减去顶行，以便每月更改一次，我不知道如何实现，或者甚至可能。我假设它是否可能通过使用表达式而不是本报告中的简单表达式

例如，电话回答％=字段！Calls_Answered.Value / Fields！Calls_Offered.Value

我有点超出了我的深度。

这可能是一个最好在SQL级别而不是SSRS级别解决的问题。如果它有用我使用的SQL查询就是这个。

SELECT
CONVERT(DATE,FORMAT([Start Time],'dd/MM/yyyy'),103) AS [Date]
,[Client Name]
,[Account]
,SUM(IIF([Type] in ('Normal operator call','Caller rang off','Caller  rang off during divert','No suitable operator logged on'),1,0)) AS [Calls Offered]
,SUM(IIF([Type] in ('Normal operator call'),1,0)) AS [Calls Answered]
,SUM(IIF([Type] in ('Caller rang off','Caller rang off during  divert','No suitable operator logged on'),1,0)) AS [Ring Offs]
,SUM(IIF([Ring (secs)] <= 20 AND [Type] in ('Normal operator  call'),1,0)) AS [Answered in 20 Secs]
,SUM(IIF([Ring (secs)] > 5 AND [Type] in ('Caller rang off','Caller  rang off during divert','No suitable operator logged on'),1,0)) AS [CRO After 5 Secs]
,AVG(IIF([Type] in ('Normal operator call'),[Ring (secs)],null)) AS 'Avg Time to Answer'
,AVG(IIF([Type] in ('Normal operator call'),[Connected (secs)],null))  AS 'Avg Call Time'
FROM InboundCallsView    
WHERE [Client Name] = (@Client) and [Start Time] >= DATEADD(m,-1,DATEADD(mm, DATEDIFF(m,0,GETDATE()), 0))    
GROUP BY FORMAT([Start Time],'dd/MM/yyyy'),[client name],[account]    
ORDER BY [Client Name],[date]

Answer 1

您可以使用SUM()函数执行IIF()，如果它符合将其置于顶行的条件，则将该度量乘以* -1。

在伪代码中，使用[Calls Answered]作为示例，它看起来像这样：

SUM(IIF({This is the top row}, -1 * [Calls Answered], [Calls Answered]))

我不知道您报告的所有可能参数，所以我不知道具体如何确定一行是否会排在最前面。您的样本结果的一种方法是检查DATEDIFF在几个月内（[Date]和GETDATE（）之间）是否为零。
