Thanks for the feedback - I've been playing around with global hints....

I can get a very basic example working but what I want is subtley different.

Global hints allow me to influence a join method for a table inside a view, but what I want to do is to influence the optimizer to use a HASH join when joining to a table which is merged into the top level query.

e.g. the view joins table A and table B, and the calling (outer) query joins table X and the view. Table B is merged into the outer query so I want to get the optimizer to join table X to table B via a HASH join. I can't seem to get this to work via a global hint.

Do you know if this is achievable...?
