I want to get the Len of a list in expression binding but I can’t find any function for that.
Is it possible to do this by expression language?
What do you mean with a “list”?
If you mean a dataset, the
len() function just works like you’d expect. It counts the number of rows.
No I mean json array property in perspective.
This isn’t currently possible. It’s on our list to add general support for collections to expression operators.
