Using a DAX query to show a table in Power BI |
---|
Did you know that you can write an EVALUATE DAX query in software like DAX Studio and then run it from within Power BI to create a new table? You do now! |
So here's something I didn't know was possible. Whether it's useful is another question! Let's say you've written a DAX query in an application such as DAX Studio:
-- list out a set of rows
EVALUATE
SUMMARIZE(
ADDCOLUMNS(
-- show all the purchases made in London
FILTER(
Purchase,
RELATED(Region[RegionName])="London"
),
-- with an additional column showing the town name
"Town",
RELATED(Town[TownName])
),
-- group by the town name ...
[Town],
-- ... and show total quantity
"Total quantity",
SUM(Purchase[Quantity])
)
When you execute this DAX query, it lists out data from a Power BI data model:
The query shows results like this.
You now want to show this as a table in a Power BI report. To do this, use the New Table button:
You can find this New table button on the Modeling tab of the ribbon.
Paste in your DAX query, excluding the EVALUATE command at the start:
Your query should now return a table of data in Power BI.
This shows the same table of information!
You can now treat this as any other table in Power BI.
I would guess that this technique might be useful for people who know the DAX querying language but aren't as familiar with Query Editor.
