I'm trying to understand why the following DAX expression executed in DAX Studio returns a blank rows. I don't see an explanation in the documentation about this. I'd prefer not to have any rows returned vs a blank one.
DEFINE
table t = {(1)}
var _filter = filter(t,[Value]>1)
evaluate {
Calculate(
Minx(_filter,[Value]))
}
Furthermore, why this expression returns 1? I thought Calculate applied the filter prior to the expression.
DEFINE
table t = {(1)}
var _filter = filter(t,[Value]>1)
evaluate {
Calculate(
Minx(t,[Value]),
filter(t,[Value]>1)
)
}
Solved! Go to Solution.
Hey @sbuster ,
as you figured out DAX Studio will show at least one row.
It is blank because the result returns a blank table.
Your second example returns also blank for me. Can you double check if it returns 1 for you?
If you need any help please let me know.
If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
Best regards

I disccovered DAX Studio is returning a single row because I'm using the table constructor with no value, which will produce a single row with no value...

The second example definitely returns 1 for me. My assumption in the second example is that Calculate will call the filter function, which has argument t, first. Then it will call Minx, which I do have as the first argument hte original table t. How would the filtered table (the result of the filter funciton within Calculate) be passed into the Minx function?
