How odd, because that's clearly NOT what I said. In fact I used the
single "a" to describe the project I was looking at where having a
default table fill factor of < 100 would be very useful. OTOH, I have
stats databases that have only insert and drop child tables that would
not benefit from < 100 fill factor. For a heavily updated database,
where most of the updates will NOT be on indexed columns, as the ONE
project I'm looking at, a default fill factor would be quite a time
saver.
