Union all very slow.

All,

 

I am having some problems with a union all view.

 

During my debugging, I commented out either the top or bottom part of
the union all

, and my queries run in a second or two.

 

When I keep both parts of the union all, the query takes 10 minutes.

 

Any thoughts on a hint?

 

Thanks

Randy
