i dont think they are totally removing the RBO from 10g. Ive seen conflicting reports. I think tom kyte hinted that it is gone, then I read somewhere else that its still going to be there.
RBO is necessary if you use layered complex views. CBO often times doesnt hold up. Its a pretty bad design. But some people use it. I see it mostly with cross-platform apps. They tell you to always use RBO. if the RBO is totally gone they will need to totally re-architecture their products. So I dont know if Oracle will do this. > > From: [EMAIL PROTECTED] > Date: 2003/10/07 Tue PM 02:04:31 EDT > To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> > Subject: Re: Desupport of RBO > > OK, dumb question.
