DAX 子查询度量？

Question

我正在努力处理 DAX 查询，想知道您是否可以提供帮助？

考虑这个 table（或可视化）称为 'Builds':

Build....App....Status
Build1...App1...UAT
Build1...App2...Complete
Build2...App1...Complete
Build2...App2...Complete

我想添加一个名为 'AppsOutstanding' 的度量列，以显示该构建的非 'Complete' 的应用程序计数。像这样：

Build....App....Status......AppsOutstanding
Build1...App1...UAT.........1
Build1...App2...Complete....1
Build2...App1...Complete....0
Build2...App2...Complete....0

我几乎需要做一个 'subquery' 测量！？类似于：

SELECT COUNT(Status) FROM Builds
WHERE Build = [The Build In This Row]
AND Status <> 'Complete'

我有点困惑如何将其转换为 DAX？这是我不成功的尝试：

AppsUnavailable = CALCULATE (
    count(Builds[Build]),
    CALCULATETABLE (
        SUMMARIZE ( Builds,Builds[Status] ),
        Builds[Status] <> "Complete"
    ))

提前致谢！

我试过了，但计数不起作用，而且这个 DAX 从我的实际结果中过滤掉了“完成”状态！我不想要的。我只想从计数度量中过滤掉“完成”状态....

AppsUnavailable =
CALCULATE (
    COUNT ( Builds[Build] ),
    FILTER (
        ALL ( Builds[Build] ),
        Builds[Build] = SELECTEDVALUE ( Builds[Build] )
    ),
    FILTER (
        ALL ( Builds[Status] ),
        Builds[Status] <> "Complete"
    )
)

我认为我做的事情从根本上是错误的。我真的很愚蠢，只找到其他同名的 'Builds'，但它仍然只有 returns 个 1！

AppsUnavailable =
CALCULATE (
    COUNT ( Builds[Build] ),
    FILTER (
        ALL ( Builds[Build] ),
        Builds[Build] = SELECTEDVALUE ( Builds[Build] )
    )
)

此查询（在单个 table（无连接）样本上进行测试时）生成此：

Build....App....Status......AppsOutstanding
Build1...App1...UAT.........1
Build1...App2...Complete....0
Build1...App2...UAT.........1
Build2...App1...Complete....0
Build2...App2...Complete....0

但我确实需要这个：

Build....App....Status......AppsOutstanding
Build1...App1...UAT.........2
Build1...App2...Complete....0
Build1...App2...UAT.........2
Build2...App1...Complete....0
Build2...App2...Complete....0

所以 Build1 有 2 个应用程序不完整。

然后我需要研究为什么我在 'live' 环境中得到全 1。它必须与过滤 2 tables 而不是 1....

您可以将 [The Build In This Row] 替换为 SELECTEDVALUE ( Builds[Build] )。试试这个：

AppsUnavailable =
CALCULATE (
    COUNT ( Builds[App] ),
    FILTER (
        ALL ( Builds[Status], Builds[Build] ),
        Builds[Build] = SELECTEDVALUE ( Builds[Build] )
            && Builds[Status] <> "Complete"
    )
) + 0

powerBI Table 可视化内部使用 SUMMARIZECOLUMNS，它从度量中删除了没有数据的行。您有 2 个选择： - 右键单击 GroupBy Column -> “显示没有数据的项目” -在最后一个括号

后的计算中添加+0

更新：

CALCULATE (
    COUNT ( YourTable[App] ),
    FILTER (
        ALL ( YourTable[App], YourTable[Build], YourTable[Status] ),
        YourTable[Build] = SELECTEDVALUE ( YourTable[Build] )
            && YourTable[Status] <> "Complete"
    )
) + 0
