SQL Error Must Declare The Scalar Variable
Mar 28, 2012I have been stuck for a long time on this simple but obtuse message "Must Declare the Scalar Variable"
I have a vb.net and SQL code that inserts data into a simple table. It works OK with sample data, but when I try to use a parameter (insertcommand.Parameters.Add("@ID", SqlDbType.Int, 3).Value = 50) it gives me the error. If I replace the @ID with just a number it works.
Eventually .Value = txtid.text if I can get the parameter to work.

Asp.net - Must Declare Scalar Variable When It Is Already Defined And Sytax Error Near 'nvarchar' When Updating
May 16, 2012Solution at the bottom. I receive the following error when trying to update records: Must declare Scalar Variable @PaymentTermID Problem is, @PaymentTermID should be defined already in the Update parameters. The 2 functions for onrowdatabound and onrowupdate are tweaked versions of the ones found here for the DropDownList: GridViewRow.DataItem Property. Delete works fine. No new lines are added, just names changed around. I am not exactly used to working with asp objects.

Asp.net - Must Declare Scalar Variable?
Oct 21, 2011I have been debugging my code for a while and looking at posts in other forums, but it seems to be that everyone has a different problem than mine and what works for them will not work for me.My dropdown list is supposed to filter a gridview by choosing all the Companies that are associated to a certain product. The solution I have found online is that most people did not have DataKeyNames set in their gridview. I do have this set, but not to CompanyID. It wouldn't make any sense. So I have no idea what I am supposed to do since this is the only answer I have found.

VS 2005 Declare Size Of Array In Structure
Dec 11, 2009I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?

.net - Update Non-scalar Entity Properties In EF 4.0?
Apr 27, 2010At first I was using this as an extension method to update my detached entities...
Public Sub AttachUpdated(ByVal obj As ObjectContext, ByVal objectDetached As EntityObject)
If objectDetached.EntityState = EntityState.Detached Then
Dim original As Object = Nothing
[code]....
Everything has been working great until I had to update non-scalar properties. Correct me if I am wrong but that is because "ApplyCurrentValues" only supports scalars. To get around this I was just saving the FK_ID field instead of the entity object relation. Now I am faced with a many to many relationship so its not that simple. I would like to do something like this...
Dim Resource = RelatedResource.GetByID(item.Value)
Condition.RelatedResources.Add(Resource)
But when I call SaveChanges the added Resources aren't saved. I started to play around with self-tracking entities but it seems they cannot be serialized to ViewState and this is a requirement for me.how to either save my many to many relationships or serialize self-tracking entities?
How To Write A Scalar Query In .NET From A SQL Database
Jul 11, 2011I am trying to write VB.NET query without writing SQL stored procs. I have already gotten many dataset text queries to work. But I am having trouble with getting this scalar query to work. All I want to do is to get the result of this T-SQL query. How can I code this successfully? select (DateDiff(w, '1/1/' + '2011', getdate())) / 7 AS SELECTED_WEEK (What this code does is it returns the current week of the year). And will this query above return the value as an integer datatype or string?
I tried your answers but it gave me this exception error:
System.InvalidOperationException: ExecuteReader requires an open and available Connection. The connection's current state is Closed.
Provide Db Scalar Methods In All Classes?
Mar 5, 2009We build a class (i.e. Server) and create a LOAD method that loads a dataset with all the details of that object.We need all that information sometimes... but what about when we only need one piece of data from that object (i.e. webserviceUrl).Should we build classes with a bunch of scalar methods that get back single pieces of data as opposed to only getting ALL the data and then only taking what we need?It's a waste to get all the data when we dont always need all of it but it also will take longer to write the extra methods..
