Yes. Whats happening currently is that expression is calculated in a view. Those tables are large OLTP tables and only the subsets in view. And there are so many other tables (about 15 but non OLTP) joined to this view and I'm applying the filter on the loaddate outside the view. So, I was thinking to convert the view to a proc and limit those results on top part of the query with loaddate into the temp table inside the proc and then join that temp table to other tables to get results faster.
