I have an aspx and aspx.vb(code behind page). I am trying to upload values from dropdown list field. I am using a stored procedure in SQL Server 2012. I can get values to upload correctly if I am using int values in the table and the stored procedure. However, when I try and upload varchar values to varchar fields in the table I get the error.....Conversion failed when converting the varchar value 'Weigh-in' to data type int.

Can anyone tell me what I need to change?

ASPX page code
<td>
                                <asp:DropDownList ID="staffid" runat="server" DataSourceID="StaffNames" DataTextField="staffmember" DataValueField="staffid">
                                    <asp:ListItem Value="home">1</asp:ListItem>

The error refers to a field called 'weigh-in'
, does this column exist in the table Points?

Suggest in your stored procedure you specify your column names in the insert statement:

INSERT INTO Points (StaffId, GroupId, WeekId, PointsId, PointsStandard, PointsBonus)
      VALUES (@staffid, @groupid, @weekid, @pointsid, @points_standard, @points_bonus)

obviously making sure that the column names shown above match your column names in your points table.

I recommend you to print the parameter values before you call the sp and then try to see if it works with your procedure directly from query window. The sp looks straight forward but the mapping of the parameters in the asp code might give problems.

Very good point. I did just that and it failed in the stored procedure so I will focus on the SQL.

USE [Wellnes2014]
GO

DECLARE      @return_value int

EXEC      @return_value = [dbo].[UpdatePoints]
            @staffid = 1123,
            @groupid = N'ee',
            @weekid = N'ee',
            @pointsid = N'ee',
            @points_standard = 345,
            @points_bonus = 3

SELECT      'Return Value' = @return_value

GO

Are you sure that your groupid, weekid, and pointsid columns are varchar it appears one of these are the problem during the update.
To track down which one you could give each a unique value rather than all 'ee' so you can find out which one is causing the problem

What is that 'ee' value? Another thing is that all the parameters that were assigned the 'ee' value are of carchar type even though they are IDs and the error is about converting 'ee' varchar to int. :


      @groupid AS varchar(150),
      @weekid varchar(150),
      @pointsid varchar(150),


I guess those 3 parameters have to be of type int, or at least one. Check the type in the Points  table and match the parameters type. After that make sure that the app assigns the right values to those parameters, instead of 'ee'.

That is exactly my point. There is no conversion to do. I am going to drop and rebuild the table and see what happens.
