SSMS SQL - AVG在PIVOT中返回总计，而不是平均值

好吧，这个很难。我确信一些使用PIVOT声明是答案，但我不够知识足以形成正确的查询。我认为AVG也扔我循环。活跃的当月SSMS SQL - AVG在PIVOT中返回总计，而不是平均值

我有一个查询将返回正是我想要的，但它给出了结果的成员

我要找的只是每个月的总成本/数量每行一个月的时间段的形式，我希望将每月的时间段的平均值作为列标题。

我已经得到建立一个动态查询，以指定所需的字段的手段用于列标题，并在使用SELECT和PIVOT查询报表，并能正常工作，而相反而不是平均，查询似乎只是简单地提供那段时间的付款。

在下面的代码中，第一个查询CTE的结果包含正确的信息，但是包含行，而不是列。实质上，我需要能够透视数据以提供每月期间（Eff_Period）作为列标题和特定期间的平均成本（，PMPM）作为列的值。

这是整个查询与示例临时表中声明和填充使用它（我希望我是这样做的权利）;

第二个查询的形式是正确的，它只是它似乎是提供SUM S，而不是AVG秒。

我没有那么多需要的答案，因为一个人说，“spoonfed”给我;只是一些迹象表明我在做什么错在PIVOT查询将是有帮助的。

其实，编辑是错误的。在医疗保健行业，被称为PMPM的供应商有一个价值;每个成员每月。这不是每个成员的价值，而是一种手段，看看每个成员在整个设施上花费了多少。因此，如果10月份的医疗费用为200美元，而当月有50名活跃成员，则PMPM为200美元/ 50美元，即4美元。没有列出每个成员，但是按医生，设施，医院分组，无论哪个实体的价值正在确定。重读我发布的内容，尽管如此，我本可以更好地说明这一部分。 – AdamQuark

编辑：提供结果集作为月内索赔平均数/会员数的方法。

真是太棒了！如果我理解正确，我认为以下内容应该有助于指导你。无论是否在当月提出索赔，它都会输出全年电网。

请注意，我删除了动态SQL部分，因为我将该部分留给您解释，以利用下面的旋转结果作为输入。我也硬编码在第二CTE特定年份过滤器，它可以用一个变量替换平凡和/或变得更为复杂考虑到月，日等

;with memberClaimsByMonth as 
(
    select 
     m.MemberID as MemberId 
     ,year(c.Clm_dt) as ClaimYear 
     ,month(c.Clm_dt) as ClaimMonth 
     ,c.Clm_Amt as ClaimAmount 
    from 
     #Mbr_Data m 
    join 
     #Clm_Data c 
     on c.Mbr_ID = m.MemberID 
), 
memberAvgClaimByMonth as (
    select 
     c.ClaimMonth 
     ,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

我认为关键外卖是PIVOT利用AVG()在今年的所有月份。要动态过滤，可以将数据透视查询封装到CTE中（或将结果放在临时表中），并使用动态sql获取要查找的列（月）。

Thanx的帖子，pim，我现在摆弄它。您的代码为每个成员分别提供一行，但我只查找每个月的总费用/当月活动的成员数量。我修改了代码来返回一行，但我不知道它是如何得到它的值。仍在努力。我会发布我修改它的方式，但似乎并不是注释字段中的一个选项。 Thanx再次，但我会插在上面！ – AdamQuark

@AdamQuark我将更新我的回复。坚持下去。 – pimbrouwers

@AdamQuark我已经更新了我的回复，其中包括第三个cte和对第二个cte组的修改。我认为这更接近你要找的东西。 – pimbrouwers
