Move data from one oracle db to another db using toad
If you have Toad I assume you can connect to both databases from it.  


Select the origin table in the schema browser in Toad, right click, select "Create in another schema" or "Copy Data to another schems".
A dialog box appears, select your options as required.
then a "Destination" dialog box appears.  Select the connection to the destination database and schema of your choice
Click on execute.


Toad will show a failure or success message.

Job done!
