A view won't do what you want, because the macro expansion occurs when the CREATE VIEW is executed; the macro is not resolved at the time the view is accessed. If you absolutely must have view access-time resolution of the WHERE or HAVING clauses, you'll have to rely on EVAL() for it.

An alternative might be to create the view you need in a temporary DBC just before it is needed; you'd use a temporary DBC because the DBC would bloat over time from multiple CREATE VIEW and DELETE VIEW sequences, and to allow several people to work with their own unique view definition at any given moment.
