SQL Server :: How To Set A Optional Parameter To NULL
Oct 29, 2010
I 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.

I have the following scenario: my website displays articles (inputted by an admin. like a blog).So to view an article, the user is referred to Home/Articles/{article ID}.However, the user selects which article to view from within the Articles.aspx view itself, using a jsTree list.So I what I need to do is to be able to differentiate between two cases: the user is accessing a specific article, or he is simply trying to access the "main" articles page. I tried setting the "Articles" controller parameter as optional (int? id), but then I am having problems "using" the id value inside the controller.

I was expecting a parameter will become a empty string value if the parameter is missing, but it turn out to be null. have I done it wrong for the optional parameter?
I am using NLog for logging in an ASP.Net application and making use of the database target with Microsoft Sql Server.I have some logging parameters that are optional and not always specified. I would like these to be written as null when they are not provided, however NLog seems to always write them as empty strings.
Is there a way to configure it to write null as the default?
I'm creating a reports with the following filter criteria:
ID - textbox Created Date - range between start and end date Syste Name - dropdown Users may filter the report based on the ID or System Name or all the criteria mentioned.
The search Field for ID, by default has a Null checkbox beside on it while other filter doesn't. how can I enable the checkbox for the other filters?
So I came across this article which should my issue. Apparently, I'm receiving a formula error "The arguments to the following functions are not valid:FIND" with this formula OR(FIND(Creation Date, Parameter: Creation Date)<>0, Parameter : Creation Date = Empty). see this link for the screenshot.

I'm trying to have a parameter as optional i.e. /Category/{ProductName}/{ProductOption} where ProductOption is optional. How do I handle this in web forms 4? Here's what my code looks like now:
I have a vb.net page that has an optional parameter. If a user enters data for that field, and clicks save, it saves fine via the stored procedure. HOWEVER, if the user changes their mind, and wants to erase the data they entered, they go to the text field, and delete the characters, and click save, but no matter what, the stored procedure will not save the fact that they erased the data (it won't set it back to NULL). If the user enters a space, the stored procedure will save the space, and if they enter different data, it will save the other data. I can't figure out how to get it back to letting them set it to Null? I think this is because it's an optional parameter, and the stored proc is used by several forms (Some of those forms do not include this parameter), but this form utilizes that optional paramater.
