2. Install the updated Tableau Driver package.

Redshift

  1. Uninstall Tableau Redshift drivers from /Library/ODBC/odbcinst.ini

Presto:

Oracle

  • For Tableau 2020.2 and newer, Oracle JDBC drivers are not impacted and will continue to work.

Lisäresurssit
This error can also be encountered when connecting to an Amazon Redshift database if Redshift drivers are not installed, as Desktop will attempt to fallback to the PostgreSQL driver.
