Glenn,

You say
"...you probably can maintain an index on Deleted()because there are so few so as not to create a problem.".

But that is precisely the problem - with only a small percentage of entries that *are* Deleted(), then given a reasonably large number of records performance will be adversely affected every time when running with DELETED set ON.

It is NOW known that an index on DELETED() is a bad thing *most* of the time.

Cheers,

JimN
