Dropbox JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Dropbox cloud storage data including Files, Folders, Users, and more!



Access and validate Dropbox data in QuerySurge using the CData JDBC Driver.

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for Dropbox, QuerySurge can work with live Dropbox data. This article walks through connecting to Dropbox data from QuerySurge.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Dropbox data. When you issue complex SQL queries to Dropbox, the driver pushes supported SQL operations, like filters and aggregations, directly to Dropbox and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Dropbox data using native data types.

Connecting to Dropbox Data in QuerySurge

To connect to live Dropbox data from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.

Deploy the JDBC Driver

  1. Download the CData JDBC Driver for Dropbox installer, unzip the package, and run the JAR file to install the driver.
  2. Once the driver is installed, stop the Agent Service.
  3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Dropbox\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
  4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to Dropbox

  1. Log into QuerySurge and navigate to the Admin view.
  2. Click Configuration -> Connections in the Administration Tree.
  3. Click Add to create a new connection.
  4. In the QuerySurge Connection Wizard, click Next.
  5. Name the connection (e.g. CData JDBC Connection to Dropbox).
  6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
  7. Set the Driver Class to cdata.jdbc.dropbox.DropboxDriver and click Next.
  8. Set the Connection URL using the necessary connection properties to authenticate with Dropbox. Your Connection URL will look something like the following:

    jdbc:dropbox:InitiateOAuth=GETANDREFRESH

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.dropbox.jar

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

    Dropbox uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Dropbox.

    See the Getting Started guide in the CData driver documentation for more information.

  9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Files LIMIT 1) and click Next.
  10. Click Test Connection to ensure the connection is configured properly and click Save to add the connection.

Once the connection is added, you can write SQL queries against your Dropbox data in QuerySurge.

Compare Dropbox Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying Dropbox data with a QueryPair.

  1. Select "Design Library" from the Design Menu
  2. Click QueryPairs under QuerySurge Design
  3. Click "Create New QueryPair"
  4. Name the QueryPair and click Save
  5. In either the Source or Target panes, select the connection created above (select the same connection to query Dropbox twice or another connection to perform a comparison)
  6. Write queries in the Editor for each pane, e.g. SELECT * FROM Files
  7. Click the "Design-Time Run" tab to execute the queries
  8. When the query execution is finished, click "View Query Results" to see the Dropbox data returned by the query
