SSMS SQL - AVG在PIVOT中返回總計，而不是平均值

好吧，這個很難。我確信一些使用PIVOT聲明是答案，但我不夠知識足以形成正確的查詢。我認爲AVG也扔我循環。活躍的當月SSMS SQL - AVG在PIVOT中返回總計，而不是平均值

我有一個查詢將返回正是我想要的，但它給出了結果的成員

我要找的只是每個月的總成本/數量每行一個月的時間段的形式，我希望將每月的時間段的平均值作爲列標題。

我已經得到建立一個動態查詢，以指定所需的字段的手段用於列標題，並在使用SELECT和PIVOT查詢報表，並能正常工作，而相反而不是平均，查詢似乎只是簡單地提供那段時間的付款。

在下面的代碼中，第一個查詢CTE的結果包含正確的信息，但是包含行，而不是列。實質上，我需要能夠透視數據以提供每月期間（Eff_Period）作爲列標題和特定期間的平均成本（，PMPM）作爲列的值。

這是整個查詢與示例臨時表中聲明和填充使用它（我希望我是這樣做的權利）;

第二個查詢的形式是正確的，它只是它似乎是提供SUM S，而不是AVG秒。

我沒有那麼多需要的答案，因爲一個人說，「spoonfed」給我;只是一些跡象表明我在做什麼錯在PIVOT查詢將是有幫助的。

讓我提前說，任何幫助將不勝感激。感謝名單！

其實，編輯是錯誤的。在醫療保健行業，被稱爲PMPM的供應商有一個價值;每個成員每月。這不是每個成員的價值，而是一種手段，看看每個成員在整個設施上花費了多少。因此，如果10月份的醫療費用爲200美元，而當月有50名活躍成員，則PMPM爲200美元/ 50美元，即4美元。沒有列出每個成員，但是按醫生，設施，醫院分組，無論哪個實體的價值正在確定。重讀我發佈的內容，儘管如此，我本可以更好地說明這一部分。 – AdamQuark

編輯：提供結果集作爲月內索賠平均數/會員數的方法。

真是太棒了！如果我理解正確，我認爲以下內容應該有助於指導你。無論是否在當月提出索賠，它都會輸出全年電網。

請注意，我刪除了動態SQL部分，因爲我將該部分留給您解釋，以利用下面的旋轉結果作爲輸入。我也硬編碼在第二CTE特定年份過濾器，它可以用一個變量替換平凡和/或變得更爲複雜考慮到月，日等

;with memberClaimsByMonth as

     m.MemberID as MemberId

     ,c.Clm_Amt as ClaimAmount

     #Clm_Data c 
     on c.Mbr_ID = m.MemberID

     ,count(c.MemberId) as MemberCount 
     ,avg(c.ClaimAmount) as ClaimAvg 
    from 
     memberClaimsByMonth c 
    where 
     c.ClaimYear = 2016 
    group by 
     c.ClaimMonth 
), 
claimAvgOverMemberCount as (
    select 
     c.ClaimMonth 
     ,c.ClaimAvg/c.MemberCount as ClaimAvgOverCount 
    from 
     memberAvgClaimByMonth c 
) 

select 
    * 
from 
    claimAvgOverMemberCount c 
pivot 
(
    avg(c.ClaimAvgOverCount) 
    for ClaimMonth in ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12]) 
) p

我認爲關鍵外賣是PIVOT利用AVG()在今年的所有月份。要動態過濾，可以將數據透視查詢封裝到CTE中（或將結果放在臨時表中），並使用動態sql獲取要查找的列（月）。

Thanx的帖子，pim，我現在擺弄它。您的代碼爲每個成員分別提供一行，但我只查找每個月的總費用/當月活動的成員數量。我修改了代碼來返回一行，但我不知道它是如何得到它的值。仍在努力。我會發布我修改它的方式，但似乎並不是註釋字段中的一個選項。 Thanx再次，但我會插在上面！ – AdamQuark

@AdamQuark我將更新我的回覆。堅持下去。 – pimbrouwers

@AdamQuark我已經更新了我的回覆，其中包括第三個cte和對第二個cte組的修改。我認爲這更接近你要找的東西。 – pimbrouwers
