Using Oracle’s recycle bin

Oracle

THE BASICS

First, a quick review of the basics. There are two recyclebin views: USER_RECYCLEBIN and DBA_RECYCLEBIN. For convenience, the synonym RECYCLEBIN points to your USER_RECYCLEBIN. The recyclebin is enabled by default in 10g, but you can turn it on or off with the RECYCLEBIN initialization parameter, at the system or session level.

When the recyclebin is enabled, any tables that you drop do not actually get deleted. Instead, when you drop a table, Oracle just renames the table and all its associated objects (indexes, triggers, LOB segments, etc) to a system-generated name that begins with BIN$.

Enjoy..
