Thanks, but sorry, I didn't tell that before, the old table doesn't have indexes, and the new one should have some.

And this is a batch job that should be executed once per day.

So is it rational to recreate table and indexes each time? Or is it better to create a table with indexes once and then just empty it and fill it?
O.K. I think you should explain why you want to copy the table?

I need to copy it because I need to run a query on it that needs indexes and I can't set indexes on original table.

1 300 0002 FSEE0070000289      F0133867      N 43 2003 A1080501 000 KBUS EEK 0000 -542979,00 -542979,00
-2979,00      -542979,00 000000000000 0

Its relatively a small table.
I would go for having a second table, truncating and loading each time rather than creating a second table every time.

You may use APPEND hint to speed up the load.

insert /*+ APPEND */ into <table 2>
select * from <table 1>;
