Hello Team
I hope you are doing well.
I am trying to create a dummy column with null values in DAX.
I'm trying to do the DAX equivalent of this SQL query:
Select null as ColumnA
Do you know how I can do it in DAX?
Thanks for your help.
Solved! Go to Solution.
Hi @Anonymous ,
Please try the following dax:
EVALUATE SUMMARIZE ( Table,Table[column1],Table[column2],"newcolumn",blank())
