        If you don't do anything to the indexes, like drop them, they will be there when you load the data back. Of course, if your table is really large, then the load time will be longer.

        You may also want to investigate ALTER TABLE MOVE. Now that command will require you to rebuild the indexes.

        What are you trying to accomplish by moving, truncating, moving the data back?

Hi Friends,

Iam reorganizing my tables thru copy(CTAS), So when Iam re-inserting data into my Original table Will the indexes will build automatically or I have to rebuild?? Here Iam not doing for indexes anything i.e Iam not disabling it.

I want to create table thru CTAS, truncate original table, copy back data into original table from duplicate table. So that I can pack data and get back my space back. My environment is v7.3 on AIX.

Thanks in advance
peter.
