Flashback Table provides you with the capability to restore one or more tables to a previous point in time, essentially reverting changes that were already committed with a single command. In this video, learn how to use the FLASHBACK TABLE TO command and restore an individual table to a previous state. You will also learn how to recover an accidentally deleted table from the database recycle bin using the FLASHBACK TABLE TO BEFORE DROP command.
- [Instructor] Oracle flashback technologies…allows restoring an individual table…to a previous point in time.…Similarly to flashback query,…the flashback table feature…also relies on using data contained…in the database undo tablespace to roll back changes.…By using the flashback table statement,…we can restore an earlier state of a database table…in the event of human or application error.…Let's see flashback table in action.…We'll start by opening a connection…as the system user to the demo_pdb pluggable database…we have created earlier in our course.…
So, I'll type sqlplus…system/oracle@localhost…specifying the listener port number…and a connection to be made…to the demo_pdb pluggable database.…We'll also need to create a new tablespace.…So, let's see the location of our existing data files.…I'll type select file_name from dba_data_Files.…I'll also copy the directory…in which the data files for this pluggable database…have been created in,…so let's copy this path.…
Going to our exercise file…we can find the create tablespace command provided.…
