Hi all,
I am newbie to OCI. I am stuck into a problem related to database links in OCI. On my two separate machines, I have oracle installed (both of them 10g). I want to insert data into table which resides on database #1. The data will be get from another table which resides on database #2.
I do not know how to do it. I want to do it using OCI only. Kindly help me out!!!.

Thank you.

You can do it like if it is a local table, it does not matter the source is local or remote just use the database link inside the "insert select" statement.

Thanks Micheal for your reply.

One more question, this means that I do not have to make connection explicitly for Database #2.

Thank you.

Yes, database link makes the connection for you behind the scene. You don't have to care about it.

when using database links, the connection to the remote server is implicit and done on the fly when you first reference it in a query
