Current there is only a SQL trigger for when an entire database table has changed. It would be really useful to be able to create a Flow for an on-premise SQL database with a trigger that activates anytime a specific field in a table has been changed. For example a commonly requested alert in an EPR system would be to alert a user when the shipment date of a Sales Order has been updated. That date is a field in a table. Currently this functionality is not available in MS Flow.
