I don't use SET KEY myself, but included it for completeness sake. Several other programmers mentioned this as an alternative. I don't know why it doesn't help in your case - but I wouldn't use it for other reasons. Mainly, the advantage of a p-view, to use temporary indices (SET KEY relies on an active index).

A parameterized view helps a lot, in terms of speed, and I try to use it as soon as my form works with an underlying table of 20,000 records or more.
