Teradata JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Teradata databases.



Access and validate Teradata 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 Teradata, QuerySurge can work with live Teradata data. This article walks through connecting to Teradata data from QuerySurge.

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

Connecting to Teradata Data in QuerySurge

To connect to live Teradata 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 Teradata 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 Teradata\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 Teradata

  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 Teradata).
  6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
  7. Set the Driver Class to cdata.jdbc.teradata.TeradataDriver and click Next.
  8. Set the Connection URL using the necessary connection properties to authenticate with Teradata. Your Connection URL will look something like the following:

    jdbc:teradata:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.teradata.jar

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

    To connect to Teradata, provide authentication information and specify the database server name.

    • User: Set this to the username of a Teradata user.
    • Password: Set this to the password of the Teradata user.
    • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
    • Port: Specify the port the server is running on.
    • Database: Specify the database name. If not specified, the default database is used.
  9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM NorthwindProducts 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 Teradata data in QuerySurge.

Compare Teradata Data Queries with a QueryPair

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