I think the query is displaying data from the table in the order in which rows were inserted by SQL*Loader.
Whereas, the query to read the same data from the external table is reading the file from the first physical record. So it appears reversed..

Pradeep,
I don't know what you mean when you say SQL*Loader is "starting from
the 50,000th record and going up". If there are 50k records, are you
saying it is not loading them? Or is it reading them from 50,000 then
49,999 (i.e. in revers order)? How are you determining what order they
are being read?
Regarding external tables, the way they work is by reading the file
from the first block to either the end or till it finds what it needs.
Thus, external tables will read in the order the records are in the
file.
I stand ready for my ramblings to be corrected by anyone who can
explain better :)

Dear All,
I don't know whether SQL Loader behaves like this always or for me
only. I am loading a .dat file which has 50000 records.
I noticed that S! QL loader is starting from the 50,000th record and
going upwards, while external tables is starting from the 1st record
and going downwards.
Could somebody help me confirming this?
Regards,
Pradeep
