You may also try using the shrink space clause of alter table.

That's half way though, if you are pressed for physical disk space then
the shrink space command or an export/import of a specific table may not
help that much since the datfiles will still have the space allocated;
even if the table frees the space.


For that, I'll direct you to asktom:

Subject: shrinking space


Hi all,

Oracle on Win 2003.

SAP admitted a bug in their app, which resulted in millions of rows
inserted in a couple of tables.

They came up with a script to delete them, but failing to provide any
solutions on how to reclaim unused space. 

One of the tables has CLOB column and another has BLOB column in them.


Question: how do I shrink tables with CLOB and BLOB columns?
