Validate Google Contacts Data with QuerySurge

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

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

Connecting to Google Contacts Data in QuerySurge

To connect to live Google Contacts 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 Google Contacts 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 Google Contacts\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 Google Contacts

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 Google Contacts).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.googlecontacts.GoogleContactsDriver and click Next.

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

   jdbc:googlecontacts:InitiateOAuth=GETANDREFRESH

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.googlecontacts.jar

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

   You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

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

Compare Google Contacts Data Queries with a QueryPair

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