Configure Query Binding - Path

I have a chart opening on an embedded view, and I need to pass a view paramater to the Path of a Query. Is this just not possible ?

Sure it's possible.
Post your code. See Wiki - how to post code on this forum.

There is no code involved, just bindings.

How is it possible to achieve ?

What exactly do you mean by this?
Usually we use named queries and pass in parameters by binding.

I'm not using parameters for my query. I'm using view parameters for my embed view.

I need those params, to go to the binding of a query path. (. Path, not param )

If you click on binding for any property, you have the option to choose a binding type called "Query", in that binding type, there is a "Path".
I can only hardcode this path. Why can I not bind it to another property (view paramater for example )

Ah, OK, no, you can't do it that way but can do it by script.

The simplest way I can think of is,

  • Create a property binding on the chart. Select the view parameter using the Browse Properties button.
  • Add Transform → Script. Add code,
    return system.db.runNamedQuery(value)

(value gets passed from the original binding into the transform.)
