- Cant retreive a list column 1 answer
I wonder if someone can help me with a caml-query. I want to retreive list items from different list that has the column name "Link". But it should only retreive if the column has a value. How can I solve this with CAML-query?
Right now I tried to solve it with an if statement. But I get "undefined" and "null" because some of the list has the column name without any value or the list doesnt have the column name "Link".
