Create Oracle DBLink: Syntax & Example

In Oracle database, you can create a database link (dblink) using the CREATE DATABASE LINK statement.

The syntax for creating a database connection is as follows:

Establish a database connection named link_name, connecting as remote_user with the password remote_password using the service_name.

link_name is the name of the database link to be created, remote_user is the username for the remote database, remote_password is the password for the remote database, and service_name is the service name of the remote database.

After establishing the database connection, you can access the tables and views of a remote database by using the connection name in your query. For example, you can query the data of a table in the remote database using the following statement:

Retrieve all data from the table “table_name” linked through “link_name”.

It is important to note that creating a database link requires having the system privilege CREATE DATABASE LINK.
