    Difference in Extract when data connection is Join vs Custom SQL

    Vishal Patel

      Hi,

       

      I am trying to understand how tableau extract is created when using joins in tableau vs using custom sql.

       

      does tableau download all tables separately and join happens after or extract is one table as custom sql

       

      Thanks
