Why are you purging every night? You might be better served by copying the old data to a different database to use as a DW of sorts. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Wojciech Skrzynecki Sent: Tuesday, March 25, 2008 3:51 PM To: oracle-l@xxxxxxxxxxxxx Subject: copy tablespace in one database Hello I plan to copy data from all tables to the new tables in new tablespace every night. Why? Old tablespaces will be purged every night and I have to have old date I think that I have two options: First I have to copy tablespace to the new with new name plus date e.g. tablespace "name" to the new name_date. Second: Create tables in new tablespace "as select" but what can I do with indexes? I do not know if first options is possible. Maybe you have any idea to help me. Rgds. Wojtek
