Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
3. Click the System DSN tab.
4. Select the system data source and click Configure.
5. Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Deploying the Provider

To connect using the CData ODBC Driver for Teradata, you must install the Teradata .NET Data Provider into the GAC.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

1. Run the calling application as an administrator.
2. Connect via a User DSN instead of a System DSN.

The driver wraps the official Teradata Database driver; you can connect to the CData ODBC Driver for Teradata using the same connection properties and access the same functionality as the underlying Teradata driver.

Before You Connect

Before you can establish a connection, you must install the official Teradata .NET Data Provider into the Windows GAC. Refer to Microsoft's documentation for instructions for installing assemblies into the GAC.
