asp.net - 根据 SQL 查询在 Grid 视图中添加 Column

Question

我正在使用这个查询：

select EmployeeId, receptionist_name, date_of_sale,
  count(date_of_sale) 
from FrontOffice 
group By EmployeeId, receptionist_name, date_of_sale 
order by date_of_sale

用于填充网格视图。但我可以绑定EmployeeId, receptionist_name, date_of_sale, 所以你能告诉我如何在网格视图中绑定第 4 列以及如何填充网格视图。

更新：这是我正在使用的代码：

<Columns> 
    <asp:BoundField HeaderText="Date" DataField="date_of_sale" /> 
    <asp:BoundField HeaderText="Employe Id" DataField="EmployeeId" /> 
    <asp:BoundField HeaderText="Receiptist Name" DataField="receptionist_name" /> 
    <asp:TemplateField HeaderText="No. of Prospectus Sale"> 
    <ItemTemplate> 
        <asp:Label ID="salecount" runat="server" 
          Text='<%# Eval("SaleCount") %>'></asp:Label> 
    </ItemTemplate> 
    </asp:TemplateField> 
</Columns>

Answer 1

执行以下操作：

1. 将您的查询更改为：

   select EmployeeId, receptionist_name, date_of_sale, count(date_of_sale) as Total from FrontOffice group By EmployeeId, receptionist_name, date_of_sale order by date_of_sale

2. 将您的 Gridview 代码更改为：

   Replace Eval("SaleCount") to Eval("Total")

Answer 2

而不是更改整个代码只需将列命名为count(date_of_sale) As SaleCount

<Colums>
    <asp:BoundField HeaderText="Date" DataField="date_of_sale" />
    <asp:BoundField HeaderText="Employe Id" DataField="EmployeeId" /> 
    <asp:BoundField HeaderText="Receiptist Name" DataField="receptionist_name" /> 
    <asp:BoundField HeaderText="No. of Prospectus Sale" DataField="SaleCount" />
</Columns>
