I knew there were good reasons, I just thought I would throw that out so I could hear them. Rachel reminded me that there is also the redo log issue.

Thanks,

Why can't you just drop and recreate the table? Since I know you are an exceptional DBA this is probably a stupid question but...

    Subject: truncate a table with many extents

I'm truncating a table with around 14,000 extents on a 7.3.4 database on a slow machine. (Please don't ask how this happened, it's too=3D20 painful to re-live.)

Is there anyway to determine how far the truncate has gotten at any given point? I thought I might see changes in sys.fet$ or sys.uet$ as extents are de-allocated, but I'm not seeing that.
