Converting A Listening Table To A Listening Tickerplant?

Hey All,
I’ve been trying to work my way through converting a table (that is listening to my tickerplant) into another “tickerplant” so that I can stream data aggregations and listen to it via kdb’s C# api.

Any help greatly appreciated!

To better explain my problem:
I have successfully connected, and listened, to my tickerplant using the kdb C# api. I am trying to listen to a table listening to my tickerplant.

Should I be approaching this from the C# – can i simply pass along a “select” statement and have the table push the results to the C# on every upd?

Or is this a situation where I need to write a function within the table code and then have the C# listen to that instead of the table?

The conventional approach would be to build a chained tickerplant: http://code.kx.com/v2/kb/chained-tickerplant/

Your chained TP subscriber to the main and it’s upd function contains custom logic for manipulating the incoming data for further publishing. Then you subscribe to the chained TP for the modified data.
