Re: re-indexing per statement or per row?

Good thought for the day.
Hmmm...
On the direct path loads part I was going from memory on the documentation, but that aint't proof.

I would have to much around a bit, but I think I would do the following:

Create a dummy table with one index.
trace my session
insert a couple of 1,000 rows using one statement insert into myTable... as select...from dba_objects;
use tkprof to look at the statistics

do the same thing but with 1,000 sql statements (being lazy I would write sql to generate the sql and run that)

I would think I could deduce something from that.

I'll have to think on it more.
Thanks,
Jim
