SQL Server :: How To Set A Optional Parameter To NULL
Oct 29, 2010I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

How To Prevent Crashes When Parameter Is Null

Dim ae1 As DropDownList = FindControl("AreasExpertise1")
If (ae1 IsNot Nothing) Then
x.Parameters.AddWithValue("@areasexpertise1", ae1.SelectedValue)

View 5 RepliesGetting Null Parameter Value In Controller When MVC Route Fires?
Jan 12, 2011I'm using a custom route to create the following URL (http://mysite/subscriber/12345) where 12345 is the subscriber number. I want it to run the ShowAll action in the Subscriber controller. My route is firing and using Phil's route debugger, when I pass in the above url, the route debugger shows ID as 12345.
My controller is accepting an int as subscriberID. When it fires, the controller throws the error "The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32". Why does the route debugger show a value and the controller doesn't see it?
Here's my route (first one is the culprit)
routes.MapRoute(
"SubscriberAll",
"subscriber/{id}",
new { controller = "Subscriber", action = "ShowAll", id=0 },
new { id = @"d+" } //confirm numeric
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I'm getting a null in the ShowAll action? Here is the action method signature:
public ActionResult ShowAll(int id)
