When using SQL Passthrough, you do not have a 'live' connection to the server where updates to the data on the server are passed back to the client automatically. You need to re-issue the SQL Passthrough to refresh the local cursor to get the changes.
>I use sql passthrough to display the status of an engineering drawing on a remote database. Then I get to the remote database and change the status. Back on my local machine the dtatus is not updated until I exit the app and then start it agan.
