left anti join - expand required?

‎06-08-2022 03:17 AM

I know in some cases you have to expand the columns when doing a left outer join/merge but when doing a left anti join/merge I don't think expanding is required. Is this the best practice to follow? As when I did a left anti join i delete the table column instead of expanding it and the number of rows returned were as I expected.

Of coz the deletion of the merged column does the trick since there is nothing but nulls in the merged column from a left anti-join.


Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!
