Looking for an efficient way to create a copy of large table.

vpolasa2 days ago — edited 2 days ago

I have table with 20 columns (mostly number datatype) and 15 billion records. I would like to make a copy of this table.

In my current script, I'm using FORALL to insert 5000 records.

This script is loading at a pace of 250,000 records/second taking about 18 hours for a complete load.

Is there a more efficient way to address this through SQL script?

I'm working on :

Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production

Windows 11 Enterprise
