Re: views with parameters

Bruno, thank you for your patience, but I still don't have a clou.
Let me illustrate this with a sample from MS SQL-Server:

CREATE PROCEDURE au_info_selpub
   @pubname varchar(40)
AS
SELECT au_lname, au_fname, title, pub_name
   FROM authors a INNER JOIN titleauthor ta
      ON a.au_id = ta.au_id INNER JOIN titles t
      ON t.title_id = ta.title_id INNER JOIN publishers p
      ON t.pub_id = p.pub_id
   WHERE  p.pub_name = @pubname

EXEC au_info_selpub 'Algodata Infosystems'

This sample refers to the "pubs" database used in several bokks on MS and
Sysbase.
It returns a recordset with data in 4 columns, including column names and
data types per column.
What would be the PostgreSQL equivalent? And would I get the same results?

Thank you again
Tom Hermann

You can supply the profile ID in a where clause when you select from the
view. Is there some reason you can't do that?
