Who Am I?


Identity is the root of many challenges that arise during system usage troubleshooting, especially in situation where fine-grained attribute-based access controls are in use. Thus, it imperative that you (the identity principal) possess knowledge about how to you are being identified to a Virtuoso instance.

Basically, this is about Virtuoso's equivalent of the "whoami" command on Unix and Linux.


How to determine your Virtuoso SQL session identity, following a successful login.


  1. SQL through, for instance, iSQL:

    SELECT get_user();

  2. SPASQL (SPARQL-in-SQL) through, for instance, iSQL:

    SPARQL SELECT bif:get_user() {};

  3. SPARQL through, for instance, the /sparql input form:

    SELECT bif:get_user() {}
