Please! If you're not sure of the syntax to the point where you post something completely and utterly wrong in *principle*, why bother in the first place?

There is *no* syntax for defragmenting a tablespace. Never has been.

In Oracle 7, you have to export everything, drop everything, import everything. It isn't a cheap option, and for that reason, prevention is a million times better than cure. Consistent extent sizes per tablespace, as has been repeatedly posted here over the months, will totally prevent fragmentation (it's just a shame that you can't guarantee such consistent extents in Oracle 7 -time to upgrade to 8i where you can!).
