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.

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.

.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..

How To Deal With Execute Scalar Command That Return Null
Jan 10, 2012I want to retrieve total value from sales table in sqlcommand object. Below is my sample code.I will get error if there was no data in the tabel that matched my query saying that null could not be converted into decimal.
I would not get error if there was data that matched my query and returned the total value in tmpSales variable.My question is what is the best way to deal with this situation?
Dim CmdTmp As System.Data.SqlClient.SqlCommand
Dim tmpSales As Decimal
CmdSales = New System.Data.SqlClient.SqlCommand("SELECT SUM(Total) FROM Sales WHERE Date>= '1 Jan 2011' And Date<= '30 Jan 2011", ConDB)tmpSales = CmdSales.ExecuteScalar
Scalar Valued Function - Return Datediff As Decimal / Percent
Jan 4, 2011I am currently writing a scalar valued function and I'm having a few issue with the returned result. I have narrowed the problem down to a calculation that convert the difference between two dates as a percentage/decimal. No matter what I try the return value is always a whole number
set @earnedpremium = (@premium * @pretripearnings) + ((@premium - (@premium * @pretripearnings)) * cast((datediff(day, @outdate, @experiencedate) / datediff(day, @outdate, @returndate))as decimal(5,2)))
The cast section needs to return the percentage, I know the rest is working fine through some elimination and testing.
VS 2008 Use The Value Of One Variable To Call Another Variable Of The Same Name?
Feb 7, 2011I am trying to use the value of one variable to call another variable of the same name.I have 2 variable one called VAR1 and VAR2.
The variable VAR1 has a value of "VAR2"
The variable VAR2 has a value of "HELP"
I want to be able to get the value VAR2 from the variable VAR1 I have defined the value of VAR2 early in the code and now I want to call that value by using the value of VAR1.The reason I am doing it this way as I have a list of 50 variables that are pulled from one system. Each of these variables have the same name as the columns of a spreadsheet. The total number of Variable stay the same but the total column headers may vary each time. I need to loop through each of the column headers match them with the variable names and add the data to the spreadsheet.
VAR1 = "VAR2"
VAR2 = "HELP"
i =1
[code]....
This is the tricky bit...if the value of the cell(1,i) = "VAR2" How do I get it to display the value of the variable of the same name In this case how will I get it to display "HELP" when I only have from the VAR1 value "VAR2" I know my code will bring back the value as a string but I want it to bring back that string as a variable and display the value of that variable?
