[英]Power BI DAX: Count Distinct measure with row pair filter context
sitting on this for longer right now, this is my data:现在坐久一点,这是我的数据:
+------------+---------+------------+
| OrderID | Status | Text |
+------------+---------+------------+
| 1 | rel | W3-A |
+------------+---------+------------+
| 1 | conf | log |
+------------+---------+------------+
| 3 | rel | W3-A |
+------------+---------+------------+
| 4 | rel | W3-B |
+------------+---------+------------+
| 5 | rel | W3-C |
+------------+---------+------------+
| 6 | rel | W3-B |
+------------+---------+------------+
| 6 | conf | log |
+------------+---------+------------+
| 7 | conf | log |
+------------+---------+------------+
| 8 | rel | W3-B |
+------------+---------+------------+
| 8 | rel | log |
Now I would like to have a measure which shows:现在我想要一个显示:
=Count every distinct orderID which has (Status=rel && text= starting with "W3") but has also a row with (Status=conf && text=log) =计算每个具有 (Status=rel && text= 以 "W3" 开头) 但也有一行 (Status=conf && text=log) 的不同 orderID
That would result in a total number of "2": OrderID 1 and OrderID6 fulfilling these conditions这将导致总数为“2”:OrderID 1 和 OrderID6 满足这些条件
As table it would look like this:作为表格,它看起来像这样:
+------------+---------+------------+------------+
| OrderID | Status | Text | distinctCount
+------------+---------+------------+------------+
| 1 | rel | W3-A | 1
+------------+---------+------------+------------+
| 1 | conf | log | 1
+------------+---------+------------+------------+
| 3 | rel | W3-A |
+------------+---------+------------+------------+
| 4 | rel | W3-B |
+------------+---------+------------+------------+
| 5 | rel | W3-C |
+------------+---------+------------+------------+
| 6 | rel | W3-B | 1
+------------+---------+------------+------------+
| 6 | conf | log | 1
+------------+---------+------------+------------+
| 7 | conf | log |
+------------+---------+------------+------------+
| 8 | rel | W3-B |
+------------+---------+------------+------------+
| 8 | rel | log |
-------------+---------+------------+------------+
TOTAL 2
So Dragging the measure in a "Card" visualisation should simply show因此,在“卡片”可视化中拖动度量应该简单地显示

You can find the IDs that satisfy each set of conditions and then take the intersection to find which of them satisfy both.您可以找到满足每组条件的 ID,然后通过交集找出满足这两个条件的 ID。
DistinctCountPairs =
VAR rel_W3 =
CALCULATETABLE (
DISTINCT ( Orders[OrderID] ),
Orders[Status] = "rel",
LEFT ( Orders[Text], 2 ) = "W3"
)
VAR conf_log =
CALCULATETABLE (
DISTINCT ( Orders[OrderID] ),
Orders[Status] = "conf",
Orders[Text] = "log"
)
RETURN
COUNTROWS ( INTERSECT ( rel_W3, conf_log ) )
If you want, you can switch the final line to如果需要,可以将最后一行切换为
CONCATENATEX ( INTERSECT ( rel_W3, conf_log ), Orders[OrderID], "," )
to print a list of which IDs are in the intersection.打印交叉点中的 ID 列表。
