Access data remotely by creating a database link.
Because Oracle Application Express runs in the Oracle database, you have access to all distributed Oracle database capabilities. Typically, you perform distributed database operations using database links.
A database link is a schema object in one database that enables you to access objects on another database. Once you have created the 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.
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.
To create a database link:
Object Browser home page appears.
Note that Database Link names must conform to Oracle naming conventions and cannot contain spaces, or start with a number or underscore.
