Hi list
I've got a large fact table and kind of snowflaked dimensions. I need to go from one dimension through fact into the other dimension. I'm trying to write a query which reads the corresponding partition of the fact, extracts the list of join keys, materialises this result set, and finally joins the necessary dimensions. The key thing I'm trying to do is to run the initial query on the fact in parallel and then the rest of the query serially. In other words I need to run one DFO in parallel and the other serially. Now with the last bit I'm stuck and can't find the way to do it. Does anyone know if that's possible at all? I'm using Oracle 11.2.0.3 on Linux x64.
