Question

我在ASP.NET Gridview中添加了一个按钮列，如此，

<Columns>
   <asp:TemplateField ShowHeader="False">
      <ItemTemplate>
         <asp:Button ID="btnBlacklist" runat="server" CausesValidation="false" CommandName="Pass"
                     Text="PASS" CommandArgument ='<%# Eval("ACCOUNT_ID")%>'/>s
      </ItemTemplate>
    </asp:TemplateField>
</Columns>

在后面的代码中，添加了类似的触发事件，

Protected Sub gTransReport_RowCommand(sender As Object, e As GridViewCommandEventArgs)

    If e.CommandName = "Pass" Then
        Dim accountId As Integer = Convert.ToInt32(e.CommandArgument)

        DbConn = New OleDbConnection()
        Try
            dbdll.ConnectDB(connString, DbConn)
            If DbConn.State <> ConnectionState.Open Then
                DbConn.Open()
            End If
        Catch ex As Exception
            ClassMC.putToErrorLog("[" & Session("USER").ToString().Trim & "] " & ex.Message & ex.StackTrace)
            Session("ERRORDESC") = ex.Message & " " & ex.StackTrace
            Page.Response.Redirect("ZapError.aspx")
        End Try
        Try
            Using dbCommand As New OleDbCommand("UPDATE AML_INDIVIDUAL_PERCENTAGE SET SECOND_NAME = 'PASS' WHERE ACCOUNT_ID = '@accountID'", DbConn)

                dbCommand.Parameters.AddWithValue("@accountID", accountId)
                dbCommand.CommandType = CommandType.Text
                dbCommand.ExecuteNonQuery()
            End Using
        Catch ex As Exception
            ClassMC.putToErrorLog("[" & Session("USER").ToString().Trim & "] " & ex.Message & ex.StackTrace)
            Session("ERRORDESC") = ex.Message & " " & ex.StackTrace
            Page.Response.Redirect("ZapError.aspx")
        Finally
            DbConn.Close()
        End Try
        lblBlacklist.Text = "User passed!!"
    End If
End Sub

带有报告的GridView显示正常，但是当我单击PASS按钮时，会抛出ORA-01722: invalid number错误。我的数据库架构ACCOUNT_ID是NUMBER。我调试了我的代码，并且不知道为什么抛出这个错误，帮助。

不要将参数包装在像这里的撇号中那样：

 WHERE ACCOUNT_ID = '@accountID'

代替：

 WHERE ACCOUNT_ID = @accountID

否则字符串@accountID将用作accountID的值，而不是数字。

更新：oracle中的afaik

 WHERE ACCOUNT_ID = :accountID

按钮CommandArgument Error，ORA-01722的ASP.NET Gridview列：无效的数字
