Limitations and Requirements

Note

During normal selection or import of an entire table, you may encounter an error indicating a problem with a specific column. Since some tables require filtering based on a particular column, data from them can only be ingested using custom SQL statements. In this case, the problematic column can be used as a filter in the WHERE clause of a custom SQL statement to ingest the table.

  • For more information, please consult the CData driver documentation for the specific table.

  • For more information on using custom SQL, see Create Dataset with SQL.

Note

For filtering date columns, this connection type supports a set of literal functions on dates. You can use these to reduce the volume of data extracted from the database using a custom SQL query. For more information, see the pg_dateliteralfunctions.htm page in the driver documentation for this connection type.

  • OAuth 2.0 authentication is required.

    • An OAuth 2.0 web client is created for you in the Trifacta Application

    • You cannot create OAuth 2.0 connections via API.
