Polling SQL connection to test connectivity.
There is currently a suggestion to add this feature as the one function that should serve this purpose doesn’t currently do it.
http://bugreports.qt.nokia.com/browse/QTBUG-223
There isn’t actually a signal or any other indicator to poll the status of a connection in this case. The workaround for this is to send a query that you know will always be returned true, and if it returns false, you will know that the connection is down.
