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 !

If you do it in DAX, just be aware that the full table must be loaded into the data model. Doing it in the query-editor using M would (mostly) fold back to the server, meaning that the SQL-server does the extraction and returns only the results to PBI to be loaded.

 

So if you need to load the full table anyway, DAX would probably be faster.
