There are a number of database prerequisites you need to follow before you run your application so that your application receives the desired notification. Prerequisites to Create SQL Notification Requests Hence the notification gets executed once the result is changed. So once you run a command that has notification associated with it, the Database Engine registers the notification request to it and maps with the existing command. The Database Engine uses Service Broker to deliver notification messages. Query Notification is a new feature which lets the application wait for the notification when the underlying query changes its result. Service Broker allows to use Queue to hold messages and hence the messages are processed one by one without the caller to wait to receive the message. It is both for applications which use SQL Server instance or for applications that distribute the work into more than one SQL server instance. Service Broker uses TCP/IP to transmit messages form the network and hence allows encrypted messaging. Service Broker architecture allows you to build loosely coupled SQL Server instances so that the instances talk with each other using normal form of messaging. Let's get into it quick and build an application for you. The Query Notification feature uses Service Broker architecture to send messages to an external process.

Once the notification is received, you can poll for once to the database to get the update and re-register for the next notification. Hence, in both ways, your application gets benefited from this new feature and you don't need to poll the database every now and then to get updates.

On the other hand for ASP.NET application, there is SqlCacheDependency class which uses the same technique to invalidate the cache entry for your application when the underlying data changes its result. NET class which lets you subscribe for an event and later on when the subscribed command gets notification from SQLServer, the OnChange event of the class gets called. Query Notification is a feature that lets you subscribe for a query such that when the result of the query changes, a message is passed to the subscriber. We will talk about the Query Notification feature of SQL Server and later introduce a practical approach to get you through with the concept. Today I am going to discuss about a somewhat old but yet very useful feature introduced with SQL Server 2005. It's always nice to receive this award and without your support, I wouldn't be what I am now. Meanwhile, I got CodeProject MVP for the year 2011, it's my second time and also got Microsoft MVP for this year too. Well, it's been a nice time since I last posted in CodeProject.
