aWHOLE lot faster than<br />triggers. Because frankly, if triggers were infinitely fast, I don't<br />think we'd be
havingthis conversation. But they're not. They're<br />slow; really slow, and while we may be able to improve that
somewhat<br/>by some means, they're basically always going to be slow. Being able<br />to rewrite queries is inside the
serveris useful, and rules are not a<br />very good solution to that problem, but right now they're the only<br />thing
we'vegot.<br /></div></div></blockquote><p style="line-height: 16px; font-size: 13px; font-family: Tahoma,sans-serif;
