Re: Can user specification of a column value be required when querying a view ?

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 ?

Not in a way that PostgreSQL itself will enforce.  If you are concerned about a query running wild and taking up resources, setting statement_timeout for the user that will be running these queries is the best way forward.  A user that has general access to PostgreSQL and can run arbitrary queries will be able to craft a query that takes up a lot of system time and memory without too much trouble.
