Home -> Community -> Mailing Lists -> Oracle-L -> Re: truncate a table with many extents
I knew this topic had come up somewhere
recently, but couldn't remember where. I
thought we'd tested truncate at the same time,
and got the same result for both -- we're back
to the Rumsfeld unknown knowns.
As a thought to Waleed on why they act
differently - either it's an oversight, or the
whole truncate section of code is written
too differently to allow the change to be
inserted easily.

I think that's a recent addition though. I remeber an OakTable discussion
about this when we were
testing 'drop' on lmt's in 8 and 9.0, the tsq$ update occurred for every
extent dropped, and this
was enhanced in 9.2 to be just once at the end of the drop
