如何在 VB.NET 中对运行总计数据表中的列求和？

Question

I am currently working on a project and am running into an error that says: Syntax error in aggregate argument: Expecting a single column argument with possible 'Child' qualifier . I have a column named "Total#" in a BusinessAnalytics data table. I want to sum the column together so that I can use it to calculate a percentage of members and percentage of nonmembers. How can I fix this?

My code for a data table with running totals

        Dim decTotalNumber As Decimal
        Dim decPercentSales As Decimal
        Dim intRow As Integer

        If chkRewards.Checked = True Then
            intRow = 1 'member
        Else
            intRow = 0 'nonmember
        End If

        With BusinessAnalytics.Rows(intRow)

            .Item("Total#") += 1

            decTotalNumber = BusinessAnalytics.Compute("SUM(Total#)", Nothing)
            decPercentSales = Convert.ToDecimal(.Item("Total#")) / decTotalNumber

            .Item("%Total") = decPercentSales.ToString("P1")

        End With


        GridView3.DataSource = BusinessAnalytics
        GridView3.DataBind()

Answer 1

Your column name contains non-alphanumeric characters, so it should be wrapped in square brackets or "`" (grave accent) quotes.

Expression

So your statement should be:

decTotalNumber = BusinessAnalytics.Compute("SUM([Total#])", Nothing)
