could somebody explain me how to load data from one oracle db to another db or with in the same db to load tables under a different schema using straight sql in an efficient manner. This is plain ETL work and I have never worked with ETL scripts before. Appreciate your help
Best Regards..
If you can establish a dblink then its simple – just INSERT INTO….SELECT…
If you don’t have a dblink then it’s not possible just using SQL – since SQL only runs within a database session. Hence you’ll need some sort of scripting to start a session on the source database run queries on it then start a session on the target database and run queries there. As to what is the best way of doing that….well there’s far too many choices to give a sensible answer – especially when we don’t even know what OS you’re using.
