> I'm surprised at these responses. Please don't take offense. It appears that you have received some very informative answers in addition to the facetious ones. ( which I *did* expect. Mladen never lets me down. )
To reiterate the point of responses to your question: Running a SQL query to indicate that a table should be reorged to based upon the amount of free space it finds simply doesn't supply enough data to indicate that it's actually necessary. It probably isn't. There are a lot of tuning "authorities" that make hard and fast rules about how to find problem areas by simply running a few queries. It is unfortunately, not that simple. Or for people like Cary Millsap, Gary Goodman, Steve Adams, Jonathan Lewis and a number of others, it is, fortunately for them, not that simple. ;) Jared On Wed, 2004-01-07 at 12:49, Shrake, Jolene wrote: > I'm surprised at these responses.
