ODBC Driver for Teradata
N/A

The 16.20 version of Teradata ODBC Driver has a new code base, and many of the features found in previous versions have been completely redesigned. The new driver does not include all of the deprecated features found in previous versions of the Teradata ODBC Driver, and these features have been removed. For more information about the new driver and how its functionality compares to the previous versions of the Teradata ODBC Driver, see the "New Teradata ODBC Driver Compatibility Reference" appendix in the ODBC Driver for Teradata User Guide.

This version of ODBC Driver for Teradata includes the following characteristics:
  • Deprecated features from the Teradata ODBC Driver are no longer functional and are not supported in the new driver. There are no workarounds for these procedures, as they are obsolete. For a complete list of obsoleted features which do not work in the new driver, see the "New Teradata ODBC Driver Compatibility Reference" appendix in the ODBC Driver for Teradata User Guide.
  • ODBC install is self-contained and the installation of other Teradata Tools and Utilities products such as Teradata ICU and Call-Level Interface (CLI) is not required.
  • Installing the ODBC Driver no longer automatically migrates DSNs. DSNs belonging to the older versions of the driver will not be converted to the newly installed version of the ODBC Driver. For more information, see "Driver Migration" in the ODBC Driver for Teradata User Guide.
  • Supports the use of unixODBC and iODBC driver managers. This is in addition to existing support of Progress DataDirect Driver Manager.
  • Teradata ODBC Driver strictly adheres to ODBC specifications. Non-compliant ODBC functions found in legacy versions of TD ODBC driver are not supported by the new driver.
  • Teradata ODBC driver conforms to standard ODBC 3.8 core level specifications.
