[Tableau]Connecting data with Oracle multi language view

Initialize sql with session variable

Sometimes we connect the data with the view(VL) with the user environment variable and it will return blank row .It's because when we connect with the database.We didn't assign the environment variable. So we should alter environment session when we connect the session

ALTER SESSION SET nls_language='AMERICAN';
