This sometimes happens if you are using a version of Tableau before 2020.2 or using Kerberos on Windows. Here is a list of some common problems and steps to resolution. Note: Tableau will provide reasonable levels of customer support to assist in troubleshooting connections with JDBC drivers, but can't create or customize a connector to work with a specific JDBC driver. Some JDBC drivers might not work with Tableau. Some JDBC drivers will support the full Tableau interactive experience, while others may work only for creating extracts. Tableau provides no guarantee or warranty that using the Other Databases (JDBC) connector with any particular JDBC driver or database will be able to successfully connect and query data. Tableau supports the ability to customize your JDBC data connection, which can improve the connection experience.

Note: If you are using a version of Tableau Desktop before 2020.2, see the Driver Downloads (Link opens in a new window) page for instructions on installing Java. Starting with version 2020.2, all Tableau applications are bundled with the Java Runtime, so you don't have to install it separately. JDBC requires Java, which makes it platform-independent. This includes both official named connectors, such as Athena, and generic connector for use with other JDBC-based drivers, called Other Databases (JDBC). Tableau supports JDBC (Java Database Connectivity) drivers for several connectors.
