Replies:

You have at least 3 options now that are all feasible
 
You just need to work which is the quickest, least risk, least complexity option  - take your pick of the one that suits your requirements best.
 
Then test the solution before implementation (and test again if necessary)
 
I think export and table rename is the easiest myself but not necessarily the quickest. Don't forget to make a note of who has privs on the table and what indexes and constraints exist currently

Hi all,
 
Can i not transfer the data of the partitioned tables into a flat file and use SQL*Loader to load back the data into non-partitioned tables? Considering the amount of data that is involved, do you think this is a feasible option?
 
Regards,
Vikram.

Wondered about this so tested (using 10g not 9i) and create table compact as select * from partitioned_table definitely collapses partitions.
No 9i to test it on.
 
 

. The data so far i have gathered is this:
 
1) Online Redefinition is possible - But we do not have Primary keys - Can we do with ROWIDs? If yes, how?
2) ALTER TABLE EXCHANGE PARTITION can be feasible - But i am not much aware of this option?
3) Tried checking if Export/Import will help but i dont think this will.
