I'm trying to create a table using 'Create Table...As Select...'
The contents will then be exchanged into a partitioned table, so they need
to have the same names and datatypes.
Some of the columns in the created table are populated with zeroes will
be updated after the partition exchange,

I don't think that there is any problem here. Specifying the number of

Thanks to everyone who responded to this thread -
Option A is now to persuade the designers to remove the Number formatting
from the parttioned table,
Option B is to pre-create the working table and populate it with Truncate
and Insert /* Append */
Option B will be slower, I think, due to the

No, option B is as fast as CTAS (as long as you don't have any indexes on
the table).
Just make sure that your append hint works...
Also you have to specify NOLOGGING on table or tablespace level when doing
insert /*+ APPEND */ or use NOLOGGING hint if you're on 9i.
