Hi,
Is there any way to force the query planner to do a materialisation stage?

I have a query that joins two views, and takes 28 seconds to run.
However if I create temporary tables that contain the contents of each
view, and then join them, the total time is 1.3 seconds.

Is there a way to hint to the query planner that it should be taking
that approach?

Thanks,
Toby
