I tested this on Oracle 11.2.0.2.7. If the recyclebin is in use:
SQL> conn / as sysdba
Connected.
SQL> select value from v$parameter
2 where name = 'recyclebin'
3 /
VALUE
----------
on
SQL>
... and you create a table in a tablespace other than system:
SQL> create table tab1
2 (col1 number)
3 tablespace users
4 /
Table created.
SQL>
... it goes in the recyclebin when you drop it:
SQL> drop table tab1
2 /
Table dropped.
SQL> select original_name from recyclebin
2 /
ORIGINAL_NAME
--------------------------------
TAB1
SQL>
… and you can restore it from there if you need to:
SQL> flashback table tab1 to before drop
2 /
Flashback complete.
SQL> desc tab1
Name Null? Type
-------------------------- -------- ------------------
COL1 NUMBER
SQL>
If you do not want this to happen, add the word purge at the end of the drop table statement:
SQL> drop table tab1 purge
2 /
Table dropped.
SQL>
... then it does not go into the recyclebin when you drop it:
SQL> select original_name from recyclebin
2 /
no rows selected
SQL>
... and you cannot restore it afterwards:
SQL> flashback table tab1 to before drop
2 /
flashback table tab1 to before drop
