Hello from Maurice, newbie question sorry (i am quick though).
I am retrieving rows from a table, i wish use a condition node to test if I have zero rows returned.
I bring returned rows to data.table. the items appears when rows are returned. it is absent when no rows are returned.
I have not deduced how to frame the condition node test.
Thanks in advance
ooops, i had a function node between get table row and condition node.
when condition immediately after get table i can see data.table.count=0 so problem solved.

A Function Node would work, but also, assuming you’re putting the result of your Get Table Rows Node at the payload path of result
, you can use the count
property on that result to tell if any rows were returned. Therefore, the expression you would check against in the Conditional Node would be:
{{result.count}} > 0
