    Writeback in tableau

    Anshul Gupta

      Hi All,


      Due to requirement I need to implement writeback in Tableau, I know this is not right, but I need it. I have a postgre database and in that I had created a function which updates the record. I took help from below mentioned link.


      Writeback to reporting database in Tableau 8 - hack or feature?





      In tableau, I even created a parameter which has string data type and value is null, and passed through custom sql, I entered the value in parameter and pressed enter, but value doesn't get updated in db.


      Please help me to understand where I am doing mistake. I have checked the name of parameter, function and all. When I am running function from DB end, function is working fine.


      Please help me out..
