SQL Server :: Using SQL INSERT Command With DataGrid - Must Declare The Scalar Variable Error
Mar 28, 2011
OK, this may be a little difficult to explain, so I will try my best and post the code I currently have.
I have a table with a list of usernames. I have the list of usernames displayed on a page through a GridView. What I am attempting to do is for each username in the column "adminUsernames", I need to insert a set of values in another database table for EACH "adminUsernames" that exists. Example: There are 2 adminUsernames vales in 2 seperate rows. These are "Admin 1" and "Admin 2". For each adminUsername values (Admin 1, Admin 2), I need a row interted in another database table. Maybe the code that I have (that does not work) will help you see what is happening:
[Code]....
I keep receiving this error when running: [Code]....
I am attempting to do an insert query on a webpage for a simple member registration form I have created in vs2010. I have done this type of thing before without problem using an access database, but now I'm using a sqlexpress db created from within vs2010. This is the screenshot of my insert query:
Now, when I execute this query in the form, I get an error that says:
Must declare the scalar variable "@FirstName".Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Must declare the scalar variable "@FirstName".
Version Information: Microsoft .NET Framework Version:2.0.50727.4952; ASP.NET Version:2.0.50727.4955
At first I just had my query with all ?'s instead of @FirstName, etc in the insert statement itself, but I got an error on that as well but it was different, it just said syntax error near "?" or something to that effect. If I manually perform this query in the builder, and it pops up a window that asks for values on everything, I put something into each field and the insert works great. It just won't work with these parameters for some reason. Can someone advise what I need to do?
when I am executing an above code and click on button to insert data is shows an error message

I have a problem with SELECT COUNT query in ASP.net. I want to create CMS with articles which have categories (which have the option to be deleted). The problem is that I want to get the number of articles within the specified category so if there aren't any articles with the specified category I can proceed with the category deletion.I have the following code:
[Code]....
After I click the button "Obriši" (Delete) I receive the following error: "Must declare the scalar variable "@KategorijaID"." I understand that the problem is with parameter, but I don't know how to correct it to use it for both the "command" and "brisanje" SQLCommands.

Possible Duplicate: Use of var keyword in C# Hi, I am pretty new in C#,I would like to know the best practices in declaring variables.I know it is possible to use VAR (explicit declaration) or the DataType when declaring a variable (implicit).
I have a really simple web interface which has been created in visual studio 2010 and is connected to an SQL server running MS SQL Server 2008. I essentially want the user to be able to enter values into the two text boxes provided and when the button is clicked, these values are inserted into the relevant table in the database.
When I run the code, I get an error back saying that the 'scalar variable for @clientName is not defined.' I have altered the insert statement to fixed values rather than entering from the text boxes and this works fine (ie, replace @clientName and @serverName in the insert statement with 'xx' and 'yy' respectively). How I can define these scalar variables. I'm not to sure what i'm missing. Code below.
