  • 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  Trifacta 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.

Create Teradata Connection

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 Trifacta Self-Managed Enterprise Edition to use MULTISET tables, please contact Trifacta 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.

For more information, see Verify Operations.
