The Teradata Source Component is an SSIS Data Flow Component which connects to a Teradata database and bulk reads data from Teradata database tables. The configuration parameters are provided in the standard data flow source component dialog. The component requires installation of Teradata Tools and Utilities 13.10 and above. Install the following Teradata components:
- Shared ICU libraries for Teradata
- Teradata GSS client
- ODBC Driver for Teradata
- Teradata Parallel Transporter (Teradata PT)
- Teradata Parallel Transporter API
- Teradata PT Load Operator
- Teradata PT Stream Operator
- Teradata PT Update Operator
Teradata Tools and Utilities post-installation steps
- Define TPT and TPT64 environment variables, referencing the root Teradata Parallel Transporter folder. The default folder is: \Program Files\Teradata\Client\13.10\Teradata Parallel Transporter
- Make sure the following folders are included in your PATH:
- \Program Files\Teradata\Client\13.10\ODBC Driver for Teradata\Lib\
- \Program Files\Teradata\Client\13.10\Shared ICU Libraries for Teradata\lib\
- \Program Files\Teradata\Client\13.10\Teradata Parallel Transporter\bin
- \Program Files\Teradata\Client\13.10\CLIv2
- \Program Files\Teradata\Client\13.10\Teradata Parallel Transporter\msg
Use the parameters below to set up the component.
Select an existing ODBC connection manager. The ODBC connection manager is only used for connecting with the Teradata Parallel Transporter. The ODBC API is not used for the bulk-load process.

Specifies the number of minutes the Export driver pauses before attempting to log on when the maximum number of load and export operations are already running on the Teradata Database. The default is six (6) minutes.
How to modify the source dynamically at runtime
The Table or Statement parameters are available for setup in the data flow properties list. Follow these steps to set up an expression:
- Right-click on the data flow canvas and select the Properties menu.
- Scroll down and find the property named like [Teradata Source].[Table]. This is the property containing the source table.
- Scroll down and find the Expressions property. Set up an expression to modify the table dynamically.
