Hello Guys! I've created custom simple connector and trying to use it with Direct Discovery. I've created DIRECT QUERY in script and has successfully loaded data. But in Chart i have no calulated data (my expression looks like SUM(Field) ).
My direct query looks like:
My connector recognise all sql requests. How columns should be named in response for sql query? what should i send in response for sql query recieved from Qlik? (I know about QVX format and have SDK documentation). Right now i send all data as i do it with sql select * from MyTable. But i have no result. What am i missing?
