    Writeback in tableau

      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.

      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..

       

      Thanks,

      Anshul
