  • By default, Teradata  does not permit the publication of datasets containing duplicate rows. Workarounds:
    • Your final statement for any recipe that generates results for Teradata  should include a Remove duplicate rows transformation. 

      NOTE: The above transformation removes exact, case-sensitive duplicate rows. Teradata may still prevent publication for case-insensitive duplicates.

    • It's possible to change the default writing method to Teradata  to enable duplicate rows. For more information, contact  Alteryx Support
  • When creating custom datasets using SQL from Teradata  sources, the ORDER BY clause in standard SQL does not work. This is a known issue.

For more information on creating a Teradata  connection, see Teradata Connections.


Duplicate row error

This error occurs when duplicate rows are being inserted during publishing to Teradata .

Workaround: All inserted rows must be unique ,or the Teradata tables must be MULTISET. To configure Designer Cloud Powered by Trifacta Enterprise Edition to use MULTISET tables, please contact Alteryx Support.



  1. After you create your connection, load a small dataset based on a table in the connected Teradata . See Import Data Page
  2. Perform a few simple transformations to the data. Run the job. See Transformer Page.
  3. Verify the results.
