Hi guys,

 I have a intersection() function that return no values (image bellow)

Click to download = A new page with only []

 

My question is how can I represent that "[]" on a condition.

i´ve allready tried, is equal to null, is equal to "[]" but I get stuck with an error.

 

Thanks in advance.

Hello @JoaoSantos489 ,

the [] represents an empty array. To check if the output array contains any values you can use the empty(...) or length(...) expressions.

empty(Outputs) is equal to true

or

length(Outputs) is equal to 0
