Hi:

I have a view that I want  to require user specification for a specific column before the query starts (if that makes sense).  

Example
I want the users to be required to provide a value for ssn in the following query... 
"select * from huge_view where ssn = '106-91-9930' "
I never want them to query the view without specifying ssn.
It has to do with resources and practicality.

Is there a way to do that ?
Thanks
