Database Types for Teradata

Project description

PyPi MIT License Python3.6+

tdtypes is a Python library built atop DB API compliant library that provides an abstraction layer for Teradata Database objects and utilities.


  • This library was originally developed as a personal project. It is being made available as an open-source project in the hope that someone else might find it useful. This library does not come with any expressed or implied warranty.
  • Python2 series is no longer supported.
  • Use of older teradata and pyodbc modules has been deprecated.
  • This library is not endorsed by Teradata Inc.


Use Python’s pip utility to install tdtypes.

$ python -m pip install -U tdtypes


It is possible to customize how tdtypes library obtains a raw database connection. This might be helpful, for example, to use DB API modules other than teradatasql, or get authentication information in ways other than the default implementation. This can be done by creating module and place it in your PYTHONPATH. Please consult module for guidance on creating your own custom module.

The default implementation allows applications to either pass connection information as a parameter or get connection information from TDCONN environment variable at run-time. Either way, connection information consists of a valid JSON string as expected by teradatasql module.
