sqldependency

Consider this example: INSERT INTO [Table] (column1) SELECT value1 If I were to execute this command in SSMS, in regards to a c# forms application, what would I need to do in order to recognize this event? Something as simple as the application displaying a MessageBox when this event occurs. I just can't seem to work this one out or find any helpful data on it. I have attempted to use SqlDependency but am not having any luck. If that is the path I need to go down, can anyone help me out with understanding the concept a little better? If you want to detect changes and not just inserts you could

This is the first time I've ever needed to use an SqlDependency so I am hoping that its a stupid mistake I've made. The problem I'm having is that the OnChanged event doesn't fire when the sql table changes. No errors or anything just it doesn't fire. Here is the code public class SqlWatcher { private const string SqlConnectionString = "Data Source = CN-PC08\\DEV; Initial Catalog=DEP; User = sa; Password=******"; public SqlWatcher() { SqlClientPermission perm = new SqlClientPermission(System.Security.Permissions.PermissionState.Unrestricted); perm.Demand(); SqlCommand cmd = new SqlCommand(

I was developing this application on VB.net 2010 and SQL 2008 . I wanted the clients to be notified for updates on the db, and the application used to check the db for changes in the specified minute using a timer, which really is not efficient. I read about query notification , sqldependency , service broker , but then I read something that said they might not be efficient if I have 100 clients and I'm using query notifications to push notifications to my application. Would someone help out on what I should do, and how I can do it (would be really helpful if examples are available). Thanks in

I have a small table (approx. 200 rows) which changes all the time (couple of times per second). I was looking for a solution where i could receive notification from the database each time it changes, rather than polling it (let's say 5-10 times per second). Moreover, i would like to receive only the changed rows each time and not fetching the whole table - i have found this rather difficult to implement this utilizing SqlDependency class. Couple of things to take under consideration: I do not have control over the changes in the table nor do i have the ability to receive the data other than

I am using SqlDependecy with signalR to push notifications to client browser when there is some database changes, I followed this and this post and everything works fine in local SqlExpress version 11.0 with Local Connection String , but i have some kind of permissions problem when i connect to remote database hosted in GoDaddy with Production Connection String Working Local ConnectionString <!--<add name="NotifyConnection" providerName="System.Data.SqlClient" connectionString= "Data Source=.\SQLExpress;Initial Catalog=TestDB;Integrated Security=SSPI;" />--> Production ConnectionString <add

Is there a way to to get notifications when SQL Azure data changes or when new data is inserted? I would like to send notifications to an ASP.NET web application and push notifications to a Windows Phone. I know that the SqlDependency class and Query notifications are used to monitor SQL Server 2008 database data changes but SQL Azure doesn't support this yet. Sorry but you don't have any options available other than rolling your own notification mechanism. One of the ways you could do this is to create triggers on the table you want to monitor and test for field-level updates, store the event
