JavaScript to sense when a record has been updated in MSSQL

Hello,

I'm looking for a script to sense when a record in an MSSQL DB has been updated, to then refresh the page.  I am trying to avoid using a timer and was wondering if there is a way to do this...?

Thanks in advance!

To understand what is going on here, you need to understand the nature of the client/server protocol.  This article should help you get that part.

Executive summary: Only the client can make a request; the server cannot initiate the communication.  You almost certainly need to use a timer to drive AJAX requests to a script on the server that can sense the condition you want to detect.

This is something I have looked at myself and not implemented.  This example shows how this can work with node.js and azzure but you can substitute for your own db  http://azure.microsoft.com/en-us/documentation/articles/sql-database-nodejs-how-to-use/
