(Oracle, Sybase, SQLServer, Progress, > DB2, IDS, etc...) Actually this is not true. And it is that misconception that is the heart of what I am pointing out. The exact same code doing the exact same thing. Or put another way the exact same transaction architecture put on all of the products you list will absolutely, definitely, and unconditionally fail on one or more of them except by unadulterated luck. A wise person doesn't trust luck to make an application behave properly. What amazes me is that this mythology, mythology that you have repeated here, is so widespread. It may be widely believed ... but the fact that many repeat it does not make it so. -- Daniel A. Morgan University of Washington damorgan@x.washington.edu (replace 'x' with 'u' to respond)
