如何将SQL server 2005中的游标值检索到ASP.NET 2.0中的gridview？

我根据条件检索两个或多个表数据，因此我在SQL Server 2005中编写如下游标：

create PROC [dbo].[uspCustomerInvoiceGetlist]
    @CustomerID varchar(20)
AS
BEGIN

    SELECT DeleteStatus,InvoiceID,CONVERT(varchar(16),CreationDate,101) + ' ' +
       CONVERT(varchar(16),CreationDate,8) as CreationDate,AccountNumber,Sum(Amount) as Amount from tblInvoiceDetails where CustomerID=@CustomerID Group By InvoiceID,CreationDate,AccountNumber,DeleteStatus
END

alter procedure uspCustomerInvoiceGetlist1(@CustomerID varchar(50)) as 
    Begin
        Declare @InvoiceID int, @Balance float
        Declare MyCur Cursor for select InvoiceID from tblInvoiceHeader where CustomerID=@CustomerID
        Open MyCur
        Fetch next from mycur into @InvoiceID
        While @@Fetch_Status=0 
        Begin
        set @Balance=(select sum(Balance) from tblInvoicePaymentDetails where CustomerId=@CustomerID and InvoiceId=@InvoiceID)
print @Balance      
if @Balance!=0

        SELECT h.DeleteStatus,h.InvoiceID,CONVERT(varchar(16),h.CreationDate,101) + ' ' +
       CONVERT(varchar(16),h.CreationDate,8) as CreationDate,h.AccountNumber,Sum(h.Amount) as Amount, @Balance as Balance from tblInvoiceDetails h inner join tblInvoicePaymentDetails p on h.CustomerID=p.CustomerID and h.InvoiceID=@InvoiceID
  Group By h.InvoiceID,h.CreationDate,h.AccountNumber,h.DeleteStatus
else
SELECT DeleteStatus,InvoiceID,CONVERT(varchar(16),CreationDate,101) + ' ' +
       CONVERT(varchar(16),CreationDate,8) as CreationDate,AccountNumber,Sum(Amount) as Amount, 0 as Balance from tblInvoiceDetails where CustomerID=@CustomerID and InvoiceID=@InvoiceID Group By InvoiceID,CreationDate,AccountNumber,DeleteStatus 

            Fetch Next From MyCUr into @InvoiceID
        End
        Close Mycur
        Deallocate Mycur
    End

   dt1.Merge(dt2);        //dt1 is the DataTable 1 and dt2 is the DataTable 2

输出是这样正确的（基于条件2的两个输出更多）

但是我可以在ASP.NET2.0中绑定网格视图中的所有值（两者）。怎么可能呢？

在前端，您将得到两个DataTable。 您只需将这两个数据表合并为一个数据表。 并将DataTable与GridView绑定。 像这样合并：

create PROC [dbo].[uspCustomerInvoiceGetlist]
    @CustomerID varchar(20)
AS
BEGIN

    SELECT DeleteStatus,InvoiceID,CONVERT(varchar(16),CreationDate,101) + ' ' +
       CONVERT(varchar(16),CreationDate,8) as CreationDate,AccountNumber,Sum(Amount) as Amount from tblInvoiceDetails where CustomerID=@CustomerID Group By InvoiceID,CreationDate,AccountNumber,DeleteStatus
END

alter procedure uspCustomerInvoiceGetlist1(@CustomerID varchar(50)) as 
    Begin
        Declare @InvoiceID int, @Balance float
        Declare MyCur Cursor for select InvoiceID from tblInvoiceHeader where CustomerID=@CustomerID
        Open MyCur
        Fetch next from mycur into @InvoiceID
        While @@Fetch_Status=0 
        Begin
        set @Balance=(select sum(Balance) from tblInvoicePaymentDetails where CustomerId=@CustomerID and InvoiceId=@InvoiceID)
print @Balance      
if @Balance!=0

        SELECT h.DeleteStatus,h.InvoiceID,CONVERT(varchar(16),h.CreationDate,101) + ' ' +
       CONVERT(varchar(16),h.CreationDate,8) as CreationDate,h.AccountNumber,Sum(h.Amount) as Amount, @Balance as Balance from tblInvoiceDetails h inner join tblInvoicePaymentDetails p on h.CustomerID=p.CustomerID and h.InvoiceID=@InvoiceID
  Group By h.InvoiceID,h.CreationDate,h.AccountNumber,h.DeleteStatus
else
SELECT DeleteStatus,InvoiceID,CONVERT(varchar(16),CreationDate,101) + ' ' +
       CONVERT(varchar(16),CreationDate,8) as CreationDate,AccountNumber,Sum(Amount) as Amount, 0 as Balance from tblInvoiceDetails where CustomerID=@CustomerID and InvoiceID=@InvoiceID Group By InvoiceID,CreationDate,AccountNumber,DeleteStatus 

            Fetch Next From MyCUr into @InvoiceID
        End
        Close Mycur
        Deallocate Mycur
    End

   dt1.Merge(dt2);        //dt1 is the DataTable 1 and dt2 is the DataTable 2

将表集获取为DataSet并使用For循环进行合并：我给出了以下代码：

  DataTable dtmerge = new DataTable();
  for (int i = 0; i < ds.Tables.Count; i++)             // ds is the DataSet
  {
      dtmerge.Merge(ds.Tables[i]);
  }

DataTable dtmerge=newdatatable（）；
for（int i=0；i

假设根据条件显示两个或两个以上的表，当您希望合并并遵循相同的操作时，如何获得所有数据表。
