Connect to SQL Workbench/J

This article describes how to use SQL Workbench/J with Databricks.

Note

This article covers SQL Workbench/J, which is neither provided nor supported by Databricks. To contact the provider, see use the SQL Workbench/J support forum in Google Groups..

Requirements

• SQL Workbench/J.

• The Databricks JDBC Driver. Download the Databricks JDBC Driver onto your local development machine, extracting the DatabricksJDBC42.jar file from the downloaded DatabricksJDBC42-<version>.zip file.

  Note

  This article was tested with macOS, SQL Workbench/J Build 130, Zulu OpenJDK 21.0.1, and Databricks JDBC Driver 2.6.36.

• A cluster or SQL warehouse in your Databricks workspace.

  • Compute configuration reference.

  • Create a SQL warehouse.

• The connection details for your cluster or SQL warehouse, specifically the Server Hostname, Port, and HTTP Path values.

  • Get connection details for a Databricks compute resource.

• A Databricks personal access token. To create a personal access token, do the following:

  1. In your Databricks workspace, click your Databricks username in the top bar, and then select Settings from the drop down.

  2. Click Developer.

  3. Next to Access tokens, click Manage.

  4. Click Generate new token.

  5. (Optional) Enter a comment that helps you to identify this token in the future, and change the token’s default lifetime of 90 days. To create a token with no lifetime (not recommended), leave the Lifetime (days) box empty (blank).

  6. Click Generate.

  7. Copy the displayed token to a secure location, and then click Done.

  Note

  Be sure to save the copied token in a secure location. Do not share your copied token with others. If you lose the copied token, you cannot regenerate that exact same token. Instead, you must repeat this procedure to create a new token. If you lose the copied token, or you believe that the token has been compromised, Databricks strongly recommends that you immediately delete that token from your workspace by clicking the trash can (Revoke) icon next to the token on the Access tokens page.

  If you are not able to create or use tokens in your workspace, this might be because your workspace administrator has disabled tokens or has not given you permission to create or use tokens. See your workspace administrator or the following topics:

  • Enable or disable personal access token authentication for the workspace

  • Personal access token permissions

  Note

  As a security best practice, when you authenticate with automated tools, systems, scripts, and apps, Databricks recommends that you use personal access tokens belonging to service principals instead of workspace users. To create tokens for service principals, see Manage tokens for a service principal.
