Getting distinct values for multiple columns

Is there a way to get distinct values for multiple columns? Specifically, I want to replicate the following SQL query into PowerBI to create a new table:   SELECT DISTINCT Col1, Col2, Col3 FROM Tab...

    Abhaykumar You can also select individual columns in query editor and click Remove Duplicates.

    Hi Abhaykumar,

     

    Use DAX and in DAX the function SUMMARIZE().

    Summarize will pull out distinct values from columns.

     

    So your resultset will be new table from Summarize

    Table_Output =  Summarize(Table_IN,Col1,Col2,Col3)

     

    I hope it helps !

Hi Imke,

thanks for the hint - where do I enter the code in the querie editor? Do I have to create a new table first, or add a new step in an existing query?

 

Problem is that the querie editor shows source tables only, not the ones I caclulated.

Isn't there a Dax formula that I can use in a new table that says something like "copy all (distinct) values from Table A Column 1, and then below all (distinct) valies from Table 2 Column 1, ...."?

You CAN do it in your current query:

Add step manually by clicking the fx-sign:

 

 

But of course, this only works for tables that exist in the query editor.

If you've created them in the data view with DAX, then you won't have access to them there.

 

You might consider opening a new thread and specifically request a DAX-solution to enhance visibility of your request.
