Wait a minute! I am a fan of Oracle, but this doesn't make sense! How can _ANY_ DBMS make a claim to be production-worthy and _NOT_ take into consideration the rest of a query when a view is used in a query when building the first result set? How else can it know how to optimize the comepete querry?

Or is it just taken for granted that Oracle is a sub-optimized DBMS when it comes to using views?

What am I missing here? (I am a former MainFrame DBA, if it helps you to see where I am comming from.) Received on Mon Apr 14 1997 - 00:00:00 CDT
