Home -> Community -> Mailing Lists -> Oracle-L -> RE: truncate or drop
If they have thousands of extents... it might be better to truncate first, then drop. I've seen it take up to 4-5 hours to drop a table with thousands of extents (not my database... but a clients.) :)
If you are going to rebuild entire datafiles/tablespaces... it might just be faster to take them offline and drop them. Then rebuild the new datafiles.
If it is the entire database... rebuild it from scratch...
Hope this helps.

Subject: truncate or drop
Hi Everyone!
I am trying to empty a database with some very large tables so I can import
it again.
Which is faster, truncating or dropping the tables?
Thanks in advance,
Ruth
