HI!

I CREATED TABLESPACE WITH ITS DATAFILE.

SQL>create smallfile tablespace usmantbs datafile 'E:\oracle\product\10.2.0\oradata\orcl\usman.dbf' size 10M logging extent management local segment space management auto;

THEN I CREATED A USER AND ASSIGN THIS TABLESPACE TO HIM.

sql>create user usmanali profile default identified by usmanali default tablespace usmantbs account unlock;
sql>grant connect,resource to usmanali;

I CONNECTED WITH usmanali as USER AND CREATED A TABLE.

sql>conn usmanali/usmanali
sql>create table baseball(id number(9));

sql>select current_scn from v$database;

CURRENT_SCN
---------------------
545863

Next i deleted the tablespace including contents and datafiles.....

sql>drop tablespace usmantbs including contents and datafiles;

i dont have any backup of this datafile but my database is in archive log....

wil i get my datafile back or not? please help.............
