Re: Using VIEW to simplify code...

Right now I dynamicly generate the SQL for an incredibly ugly 4 table join based on user information client-side. I got the bright idea to create a view and then run a MUUUCH simpler client-side query on that view. The problem is that PostgreSQL apparantly runs the view FIRST and then applies the criteria AFTER assembling the whole view. I was hoping that it would rewrite the "select" in the view to include the criteria BEFORE running the view. That way it could take advantage of the indexes the way my giant-and-hard-to-maintain-client-generated-sql does. Any thoughts or suggestions? If you MUST have the giant-and-hard-to-maintain-client-generated-sql statement and its related explain, I'll produce it. I cringe at the thought of having to redact that monster, tho.
