I am thinking whether it is possible to do as bellow:
1. export the original table
2. drop the original table
3. create the partitition table with the same table name and column name .
4. import the original table with option ignore = Y
I have no idea whether the last step will be success as I don't have experience
on doing that .
Could any Xpert make a trial ? ( I don't have enterprise oracle version at this moment )
