External tables is just a reading process. It works pretty well, I used it once for more than 500 million rows (no problems).

If you have a problem loading a table using external tables, I would assume it has to do with what happens after the reading process (any transformations or insertions).

Dear All,

I have a particular requirement in the application where data has to be loaded
to the database from files which are in a fixed format. I tried using the new
feature called External Tables and had found it to work well with less number
of records. When we obtained the actual production .dat file, it contained more
than 3 million records. I found to my utter disappointment that the system was getting stuck while data was getting loaded. I waited for hours together

and it still didnt respond. A prototype with 100000 records itself took more than
1 minute to get loaded.

Do you feel that SQL*Loader would have behaved the same way. We are yet to try the same with Loader.

Thanks for all your replies, in advance.

Best Regards
Jay
