Thread: subquery in CDA?

  1. #1

    Default subquery in CDA?

    anyone knows if there is a way to define a subquery in CDA?
    I'm facing with a dataset with many rows to be reported in several charts, after specific aggregations and I want to avoid using postFetch client side, to limit the network load.
    Thanks, Luciano

    You could try passing parameters to PDI using selectors and whatnot and from there query the database in a transformation.

    I would like to post a "small tutorial" as I just learned this the other day but I've been quite busy.

    Tell me if you need any help and I'll see what I can do

    I see the logic you refer to.
    I will try your way.
    And of course, I hope I can read your post on this topic.
    Luckily, at the moment, this issue is not urgent for me.
    Thankyou very much.
