Validate MailChimp Data with QuerySurge

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

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live MailChimp data. When you issue complex SQL queries to MailChimp, the driver pushes supported SQL operations, like filters and aggregations, directly to MailChimp 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 MailChimp data using native data types.

Connecting to MailChimp Data in QuerySurge

To connect to live MailChimp 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 MailChimp 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 MailChimp\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 MailChimp

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 MailChimp).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.mailchimp.MailChimpDriver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with MailChimp. Your Connection URL will look something like the following:

   jdbc:mailchimp:APIKey=myAPIKey;

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.mailchimp.jar

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

   You can set the APIKey to the key you generate in your account settings, or, instead of providing your APIKey, you can use the OAuth standard to authenticate the application. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with MailChimp.

   See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Lists 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 MailChimp data in QuerySurge.

Compare MailChimp Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying MailChimp 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 MailChimp twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM Lists
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 MailChimp data returned by the query
