Depends on the source of the data list. If it's form data, you'll need to know the table name and add the 'app_fd_' prefix and for columns add 'c_'.
For example, if you create a datalist from a Joget Form called Requests (table name: "app_requests") and want to insert data to its "name" field. Your table name in your query should be "app_fd_app_requests" and the column should be "c_name"
If its from another source, you'll need to know the table and respective columns as normal.
