Peter,
 Unless you drop the indexes and constraints they still exist in the original table. Truncating the table will reset the HWM on the tables and indexes. The reload will generally be faster if you drop the indexes before you load the data and then recreate the indexes. Be sure to check for invalid indices after you are finished. Ron

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.
