How to connect to TaxJar Data with Squirrel SQL client



Connect to TaxJar data and execute queries in the Squirrel SQL Client.

The CData JDBC Driver for TaxJar enables you to execute queries to TaxJar data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for TaxJar data and execute queries.

Add the JDBC Driver for TaxJar

Follow the steps below to add the driver JAR.

  1. In Squirrel SQL, click Windows -> View Drivers.
  2. Click the plus icon to open the Add Driver wizard.
  3. In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for TaxJar.
  4. In the Example URL box, enter jdbc:taxjar:
  5. In the Extra Class Path tab, click Add.
  6. In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
  7. Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.taxjar.TaxJarDriver.

Define Connection Properties

Follow the steps below to save connection properties in the driver alias.

  1. Click Windows -> View Aliases.
  2. In the pane that lists the aliases, click the plus icon.
  3. In the Add Alias wizard that opens, the following fields are required for the JDBC driver:

    • Name: Enter a name for the alias; for example, CData TaxJar Source.
    • Driver: Select the CData JDBC Driver for TaxJar.
    • URL: Enter jdbc:taxjar:
  4. If you want to define any additional properties, click Properties.
  5. In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
  6. In the Specify column, select the checkboxes for the required connection properties.

    To authenticate to the TaxJar API, you will need to first obtain the API Key from the TaxJar UI.

    NOTE: the API is available only for Professional and Premium TaxJar plans.

    If you already have a Professional or Premium plan you can find the API Key by logging in the TaxJar UI and navigating to Account -> TaxJar API. After obtaining the API Key, you can set it in the APIKey connection property.

    Additional Notes

    • By default, the CData connector will retrieve data of the last 3 months in cases where the entity support date range filtering. You can set StartDate to specify the minimum creation date of the data retrieved.
    • If the API Key has been created for a sandbox API account please set UseSandbox to true, but not all endpoints will work as expected. For more information, refer to the TaxJar developer documentation.

    Below is a typical connection string:

    jdbc:taxjar:APIKey=3bb04218ef8t80efdf1739abf7257144;
  7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query TaxJar Data

After the metadata has loaded, a new tab for the TaxJar data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:

SELECT TransactionID, UserID FROM Orders WHERE TransactionID = '123'
