I don't have the admin access to both Tableau and Database. Ok I will tell you what I wanted to do.
I am having a Data source published in Tableau server. The connections are embedded and we don't have access to it. Only the through Tableau server we can access the tables and data in the published data source.
We need that data source to join with other data source which is not in tableau server. As I know we can connect to different data source in Toad data point and write a query.
Is it possible to connect to Tableau server to access that data source ?
