Access and validate Snowflake 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 Snowflake, QuerySurge can work with live Snowflake data. This article walks through connecting to Snowflake data from QuerySurge.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Snowflake data. When you issue complex SQL queries to Snowflake, the driver pushes supported SQL operations, like filters and aggregations, directly to Snowflake 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 Snowflake data using native data types.
About Snowflake Data Integration
CData simplifies access and integration of live Snowflake data. Our customers leverage CData connectivity to:
- Reads and write Snowflake data quickly and efficiently.
- Dynamically obtain metadata for the specified Warehouse, Database, and Schema.
- Authenticate in a variety of ways, including OAuth, OKTA, Azure AD, Azure Managed Service Identity, PingFederate, private key, and more.
Many CData users use CData solutions to access Snowflake from their preferred tools and applications, and replicate data from their disparate systems into Snowflake for comprehensive warehousing and analytics.

Getting Started
Connecting to Snowflake Data in QuerySurge
To connect to live Snowflake 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
- Download the CData JDBC Driver for Snowflake installer, unzip the package, and run the JAR file to install the driver.
- Once the driver is installed, stop the Agent Service.
- Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Snowflake\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
- Restart the Agent Service.
For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.
Configure a New Connection to Snowflake
- Log into QuerySurge and navigate to the Admin view.
- Click Configuration -> Connections in the Administration Tree.
- Click Add to create a new connection.
- In the QuerySurge Connection Wizard, click Next.
- Name the connection (e.g. CData JDBC Connection to Snowflake).
- Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
- Set the Driver Class to cdata.jdbc.snowflake.SnowflakeDriver and click Next.
Set the Connection URL using the necessary connection properties to authenticate with Snowflake. Your Connection URL will look something like the following:
jdbc:snowflake:User=Admin;Password=test123;Server=localhost;Database=Northwind;Warehouse=TestWarehouse;Account=Tester1;
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Snowflake JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.snowflake.jar
Fill in the connection properties and copy the connection string to the clipboard.
To connect to Snowflake:
- Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
- Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
- Set Warehouse to the Snowflake warehouse.
- (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
- (Optional) Set Database and Schema to restrict the tables and views exposed.
See the Getting Started guide in the CData driver documentation for more information.
- Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Products LIMIT 1) and click Next.
- 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 Snowflake data in QuerySurge.
Compare Snowflake Data Queries with a QueryPair
With the connection configured, you can follow the steps below to compare querying Snowflake data with a QueryPair.
- Select "Design Library" from the Design Menu
- Click QueryPairs under QuerySurge Design
- Click "Create New QueryPair"
- Name the QueryPair and click Save
- In either the Source or Target panes, select the connection created above (select the same connection to query Snowflake twice or another connection to perform a comparison)
- Write queries in the Editor for each pane, e.g. SELECT * FROM Products
- Click the "Design-Time Run" tab to execute the queries
- When the query execution is finished, click "View Query Results" to see the Snowflake data returned by the query
