When you get the data back into the process you will get all of the data (not just a part of it). If you only want to add the new rows then you will have
to do some tricky xpath manipulation to extract only the parts you want. You will also have to know how many rows are already in the database so you know what to extract. Can you not simply replace everything each time the data is submitted?
Thanks for the reply
what i am tring is to insert data from form to database
Are you storing the data as a complete transaction or taking it apart and storing the data field by field?
As Paul mentions, you will have to use xPath statements to pull the information you want from the form data and build your SQL statement.
I am attaching a simple process that uses the JDBC component to show how this can be done. It does not use a web servcie, but I hope that it will help you.
i want to update all data at a time
