How to Connect DBeaver to Oracle via a JDBC Driver

The CData JDBC Driver for Oracle implements JDBC standards that enable third-party tools to interoperate, from wizards in IDEs to business intelligence tools. This article shows how to connect to Oracle data with wizards in DBeaver and browse data in the DBeaver GUI.

Create a JDBC Data Source for Oracle Data

Follow the steps below to load the driver JAR in DBeaver.

1. Open the DBeaver application and, in the "Database" menu, select the "Driver Manager" option. Click "New" to open the "Create new driver" form.
2. In the Settings tab:
   • Set Driver Name to a user-friendly name for the driver (e.g. CData JDBC Driver for Oracle).
   • Set Class Name to the class name for the JDBC driver: cdata.jdbc.oracleoci.OracleOCIDriver.
   • Set URL Template to jdbc:oracleoci:.
   
3. In the Libraries tab, click "Add File," navigate to the "lib" folder in the installation directory (C:\Program Files\CData[product_name] XXXX\) and select the JAR file (cdata.jdbc.OracleOCI.jar).

Create a Connection to Oracle Data

Follow the steps below to add credentials and other required connection properties.

1. In the "Database" menu, click "New Database Connection."
2. In the "Connect to a database" wizard that results, select the driver you just created (e.g. CData JDBC Driver for Oracle) and click "Next >."
3. On the Main tab of the configuration wizard, set the JDBC URL, using the required connection properties:

   To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

   • Port: The port used to connect to the server hosting the Oracle database.
   • User: The user Id provided for authentication with the Oracle database.
   • Password: The password provided for authentication with the Oracle database.
   • Service Name: The service name of the Oracle database.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Oracle JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.oracleoci.jar

   Fill in the connection properties and copy the connection string to the clipboard.

   

   Below is a typical connection string:

   jdbc:oracleoci:User=myuser;Password=mypassword;Server=localhost;Port=1521;
4. Click "Test Connection ..." to ensure you have configured the connection properly.
5. Click "Finish."

Query Oracle Data

You can now query information from the tables exposed by the connection: Right-click a Table and then click View Table. The data is available on the Data tab.
