Connect to Lakebase Data in Aqua Data Studio

The CData JDBC Driver for Lakebase integrates Lakebase data with wizards and analytics in IDEs like Aqua Data Studio. This article shows how to connect to Lakebase data through the connection manager and execute queries.

Create a JDBC Data Source

You can use the connection manager to define connection properties and save them in a new JDBC data source. The Lakebase data source can then be accessed from Aqua Data Studio tools.

1. In Aqua Data Studio, select Register Server from the Servers menu.
2. In the Register Server form, select the 'Generic - JDBC' connection.
3. Enter the following JDBC connection properties:
   • Name: Enter a name for the data source; for example, Lakebase.
   • Driver Location: Click the Browse button and select the cdata.jdbc.lakebase.jar file, located in the lib subfolder of the installation directory.
   • Driver: Enter the Driver's class name, cdata.jdbc.lakebase.LakebaseDriver.

   • URL: Enter the JDBC URL, which starts with jdbc:lakebase: and is followed by a semicolon-separated list of connection properties.

     To connect to Databricks Lakebase, start by setting the following properties:
     • DatabricksInstance: The Databricks instance or server hostname, provided in the format instance-abcdef12-3456-7890-abcd-abcdef123456.database.cloud.databricks.com.
     • Server: The host name or IP address of the server hosting the Lakebase database.
     • Port (optional): The port of the server hosting the Lakebase database, set to 5432 by default.
     • Database (optional): The database to connect to after authenticating to the Lakebase Server, set to the authenticating user's default database by default.

     OAuth Client Authentication

     To authenicate using OAuth client credentials, you need to configure an OAuth client in your service principal. In short, you need to do the following:

     1. Create and configure a new service principal
     2. Assign permissions to the service principal
     3. Create an OAuth secret for the service principal

     For more information, refer to the Setting Up OAuthClient Authentication section in the Help documentation.

     OAuth PKCE Authentication

     To authenticate using the OAuth code type with PKCE (Proof Key for Code Exchange), set the following properties:

     • AuthScheme: OAuthPKCE.
     • User: The authenticating user's user ID.

     For more information, refer to the Help documentation.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.lakebase.jar
     

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

     A typical JDBC URL is below:

     jdbc:lakebase:DatabricksInstance=lakebase;Server=127.0.0.1;Port=5432;Database=my_database;InitiateOAuth=GETANDREFRESH;

   

Query Lakebase Data

You can now query the tables exposed.
