Sqldependency for stored procedure output

Hi Everyone,

In a project I have setup a SqlDependency object in c# to retrieve data from a database as PostQueryNotification. That is working OK. The query I created gets fired as event when I insert, update or delete a record in that table.

Is it possible to use SQL MessageBroker and C# SQLDependency as event for a resultset of a StoredProcedure.

What I want to achieve is that a user can set data to create a report. When the report (in memory data, not a table) is finished I want to be pushed by the database with the resultset. So the SqlDependency query cannot be set by a query on a table or view.

Can that be achieved?

What I have tried:

I haven't tried a thing yet. Since I have used it in a project I see possibilities for another project with reports where I want the output of the Stored Procedure as resultset pushed by the database.

This article by Richard Mccutchen seems to be about what you seek: https://dzone.com/articles/c-sqldependency-monitoring[^]

An alternative might be "Change Tracking", but I doubt this will work with a memory table which you use as a result set, see this article: Using Change Tracking in SQL Server 2008[^]

Unfortunately they use a Stored procedure in the SQL Dependency to see data changes in the used table in the stored procedure. I run a stored procedure in the database. That result set should be sent to the SqlDependency. So how can the SqlDependency know that there is a result from a stored procedure? It holds in memory tabledata and not a stored on device table with data
