RE: Differences between Table Move and table Export

Hmm...I think you missed the part where Jeremiah asked you what problem you were trying to solve and what you meant by "fragmentation"....

Yes, alter table move resets the HWM.  Between exp/imp and alter table move,
the latter seems far simpler. However, it would be helpful if you could
state more clearly what the problem is that you are trying to solve, what
you mean by 'fragmentation,' and your version of Oracle.  Depending on the
version, there may be other options available to you that can minimize
disruption.  Please see:
