The techniques outlined in this post are applicable to Live Connections and Multi-Table Extracts (available in Tableau 2018.3+). If you need to use Extracts and are on a version of Tableau prior to 2018.3, please see Keeping Your Extracts From Blowing Up .
Tableau has supported Stored Procedures in Microsoft SQL Server (and Sybase and Teradata) since version 8.1, and you can connect the SP parameters to Tableau parameters.
However, there are two features that don’t exist as of 9.2:
- Parameters cannot be set to match a function, such as USERNAME()
- Parameters cannot have multiple values (no array concept)
These are both feature requests that you can go vote up on the Community forum, so go there now and then come back and continue reading!
Until these features are implemented, the only way to set these values dynamically is using Tableau Server’s ability to set parameters programmatically.
