INSERT of 10 million queries under 10 minutes in Oracle?

Question

I am working on a file loader program.

The purpose of this program is to take an input file, do some conversions on its data and then upload the data into the databa

Answer 1

If you have a text file you should try SQL LOADER with direct path. It is really fast and it is designed for this kind of massive data loads. Have a look at this options that can improve the performance.

As a secondary advantage for ETL, your file in clear text will be smaller and easier to audit than 10^7 inserts.

If you need to make some transformation you can do it afterwards with oracle.
