The VIEW is just an "alias" if you will, and they are generally a good idea. -Roberto P.S.: Please trim the messages to which you respond. For this message you left dozens of lines of cruft hanging after your message (replying at the top is a bad idea too, because you lose context). Not only this is bad for the archives, but it wastes bandwidth and shows lack of respect for other people's inbox. -- +----| Roberto Mello - http://www.brasileiro.net/ |------+ + Computer Science Graduate Student, Utah State University + + USU Free Software & GNU/Linux Club - http://fslc.usu.edu/ + Boss spelled backwards is "double-SOB"
