18.9.1 About Database Links

A database link is a schema object in one database that enables you to access objects on another database.

Note:

By default, the CREATE DATABASE LINK system privilege is not granted to a provisioned workspace or database user. To use this feature, a DBA or administrator must grant this specific privilege to the database user in the user's workspace. See Creating Database Links in Oracle Database Administrator’s Guide.

Because Oracle APEX runs in the Oracle database, you have access to all distributed Oracle database capabilities. Typically, you perform distributed database operations using database links.

Once you create a database link you can access the remote objects by appending @dblink to the table or view name where dblink is the Database Link Name you specify in the Create Database Object Wizard.
