Snippet Name: Database Links: CURRENT_USER

Description: To create a current user database link, use the CONNECT TO CURRENT_USER clause in the link creation statement. Current user links are only available through the Oracle Advanced Security option.

The following syntax creates a current user database link, where dblink is the name of the link and net_service_name is an optional connect string.

A database link is a pointer in the local database that lets you access objects on a remote database. To create a private database link, you must have been granted the proper privileges.
