One of the great progress Oracle database made with 12C was the posibility of Recover a table using RMAN without the need of any knowledge of Point-In-Time Recovery and how it is really done.
12C really simplifies everything in a really nice way that allows you a quick recovery as long as you have backup of the table in question (and of course you have it… right?)
Lets start one of the scenarios creating a small Tablespace/schema/Table in our 12.1 "Non-CDB" (No container on this case, we will explore options for a PDB later on this guide)
SQL> CREATE TABLESPACE P42;
Tablespace created.
SQL> alter tablespace P42 online;
Tablespace altered.
SQL> ALTER TABLESPACE P42
ADD DATAFILE '+DATA2'

AUTOEXTEND ON; 2 3 4
Tablespace altered.

INSERT INTO TEST (id)

END LOOP;
END;
/SQL> 2 3 4 5 6 7
PL/SQL procedure successfully completed.Right, we have our "TEST" table in "P42" schema.

Table P42.TEST dropped.Now that everything is in place, lets explore the following options:
Table Recovery
Ok, lets recover the table we just dropped. I added some comments in the output to see how RMAN does the table recover.
Is a beautiful and full automatic process
We are doing the recover to a point in time, but you can also restore
to an SCN, or to a log sequence number
## Command Example ##
recover table "P42"."TEST"
until time "to_date('15/02/2019 18:18:00','dd/mm/yyyy hh24:mi:ss')"
AUXILIARY DESTINATION '/u01/oradata/AUX';
## Output ##
# RMAN starts the Restore process creating
RMAN> recover table "P42"."TEST"
until time "to_date('15/02/2019 18:18:00','dd/mm/yyyy hh24:mi:ss')"

50Table Recovery with Remap Option
Lets try now something a bit different. Maybe you didnt drop the table but delete part of it, and you want to conserve the "current" one as well as the previous version.
To do that, we can use REMAP option as below so you will have a new table called "TEST1" as result
Also, instead of using Filesystem as AUXILIARY DESTINATION, lets use +ASM Diskgroup for a faster recovery process
Since we are using +RECO wich is used for our target DB as well,
please notice how the system wont need to restore part of the
Archivelogs since they are still on the Diskgroup
## Command Example ##
recover table "P42"."TEST"
until time "to_date('15/02/2019 18:18:00','dd/mm/yyyy hh24:mi:ss')"
AUXILIARY DESTINATION '+RECO'
remap table "P42"."TEST":"TEST1"
## Output ##
RMAN> recover table "P42"."TEST"
until time "to_date('15/02/2019 18:18:00','dd/mm/yyyy hh24:mi:ss')"
AUXILIARY DESTINATION '+RECO'
remap table "P42"."TEST":"TEST1";2> 3> 4>

Ok, I think is enough for today.
Is a really good and fast way to do Table recovery.
You can of course explore more options and do Table partitions recovery or do Tablespace remap as well as Schema name remap (Schema name remap is only an option starting with 12.2)
As always, go to the usual suspects to check on more options:
https://oracle-base.com/articles/12c/rman-table-point-in-time-recovery-12cr1
I will try couple of more recovery options (back to 11g and something else in 12.2/18c) and probably come back to this one.
One of the downsides is the fact that you need the Target Database running during the process, and as far as I tried, you cant do this process pointing to AUXILIARY DESTINATION in a different system/cluster.
Something I couldn’t work out and bothers me, is the fact that I couldn’t use a directory when using Diskgroup, so the AUXILIARY DESTINATION would be ‘+RECO/AUX’ instead of just ‘+RECO’.
I was getting an error with db_create_file_dest parameter.
Maybe there is a way to specify db_create_file_dest as well in the script but didn’t manage to find it this time
