Use of FLASHBACK in Oracle

Question

I have searched for the flashback command. Somewhere it is written we can rollback the truncate operation, and somewhere it is written we can\'t rollback. Can the FLASHBACK

Answer 1

You need to have Flashback Data Archive enabled. Then the truncate could be reversed with a statement like this:

insert into <truncated_table> 
   select * from <truncated_table> as of timestamp <some time>;

Thanks to @Jon Heller for adding this useful information about the new feature:

This requires version 11.2 or higher, which introduced support for DDL statements such as truncate.
