The SqlCommand object to associate with this SqlDependency object. The constructor will set up a SqlNotificationRequest object and bind it to the command.

Exception Condition
ArgumentNullException

The command parameter is NULL.

InvalidOperationException

The SqlCommand object already has a SqlNotificationRequest object assigned to its Notification property, and that SqlNotificationRequest is not associated with this dependency.

Query notifications are supported only for SELECT statements that meet a list of specific requirements. The following table provides links to the Service Broker and Query Notifications documentation in SQL Server Books Online.
