          hi

          firstly connect with database then load data from database and first time reload data then ok.

          now disconnect with database,

          then in your script write the code for make qvd file.

          syntax is--

          Store tablename into D:\abc.qvd

          then load this qvd in your qvw file.

            That's only possible by using the direct discovery feature of Qlikview 11.2. See here for information. In every other case you will first need to extract the data from the database. That means loading it into Qlikview in-memory database.

              if i undersatnd your question properly then i think that you have to make batch file for that

               

              you have to write this in notpad

              "C:\Program Files\QlikView10\qv.exe" /r "C:\File.qvw"

              change your path as corresponding your folder  and save that file with .bat extension......

               

              to check it properly the schedule is made or not by double click on that batch file if it creates to reload your data then it corrects and schedule it properly

                Hi,
                Gysbert Wassenaar suggestion of Qlikview Direct Discovery works for you.

                 

                If you are using Qlikview 11.2, then you can use the Qlikview Direct Discovery feature, it always fetch the data from the database dynamically.

                 

                This feature is useful when your data changes frequently or you have a large data in TBs or your dashboard needs uptodate information to be displayed.  When you use this the performance would be slower, because everytime it needs to get the data from database and display the charts.

                 

                Hope this helps you.
