RE: Procedure to DROP a 700 GB Table in 10gR2 ?

Not sure, but I'd think all 3 options would be pretty fast. Seems that #3 would be the easiest unless you really want/need to get rid of the tablespace too. Just one thing to keep in mind though since you're on 10g - unless you've disabled the recycle bin, with a regular DROP statement, it won't really be dropped, but rather will just be moved/renamed into the recycle bin, so you might want to consider adding the PURGE clause too. You also might want to check for constraints first, e.g. cascading deletes.
