下面的 SQL 代码创建了一个两行表，其中一行是发票，另一行是分组付款。然而，这不是所需的表示。真正的目标是将其显示为报表，其中发票位于顶部，然后是按日期排序的付款列表。

是否可以根据显示的信息编写查询来完成此操作？（请随时索取更多信息）。任何人都可以提出一种方法吗？

这是SQLSELECT代码：

SELECT     FilteredInvoice.accountidname,
           FilteredInvoice.createdon,
           FilteredInvoice.duedate,
           FilteredInvoice.invoicenumber,               
           FilteredInvoice.statecodename,
           FilteredInvoice.totalamount_base,
           FilteredMag_Payment.mag_paymentdate,
           FilteredMag_Payment.mag_amount_base,
           GETDATE() AS Today

FROM            FilteredInvoice
LEFT OUTER JOIN FilteredAccount ON FilteredInvoice.accountid = FilteredAccount.accountid
LEFT OUTER JOIN FilteredMag_Payment ON FilteredInvoice.invoiceid = FilteredMag_Payment.mag_invoiceid

WHERE     (FilteredInvoice.statecodename <> N'Canceled')
ORDER BY FilteredInvoice.createdon

在我看来，付款信息应该与发票在同一行。您获得第二行的唯一方法是您有两次付款。由于您按发票日期排序，因此两行将具有相同的日期并彼此相邻排序。

根据您所说，我的猜测是，如果没有付款，您想按发票日期排序，如果有，则按付款日期排序。尝试：

Order by Coalesce(FilteredMag_Payment.mag_paymentdate, FilteredInvoice.createdon)

原始查询有一些奇怪之处 - 帐户 ID 名称是否真的保存在 Invoice 表中，而不是 Account 表中？从 Invoice 到 Account 的左外连接也使得看起来好像有没有相应 Accounts 的 Invoices - 假设相反会更正常，尤其是在报表报告中。

假设原始查询正确选择了所需的数据，我建议：

SELECT    FilteredInvoice.accountidname, 
    FilteredInvoice.createdon,
    FilteredInvoice.createdon AS sort_date,
    FilteredInvoice.duedate,
    FilteredInvoice.invoicenumber,
    FilteredInvoice.statecodename, 
    FilteredInvoice.totalamount_base,
    CONVERT(datetime,NULL) AS mag_paymentdate,
    0 AS mag_amount_base,
    GETDATE() AS Today
FROM    FilteredInvoice 
LEFT OUTER JOIN    FilteredAccount ON FilteredInvoice.accountid = FilteredAccount.accountid 
WHERE    (FilteredInvoice.statecodename <> 'Canceled')
UNION ALL
SELECT    FilteredInvoice.accountidname, 
    FilteredInvoice.createdon,
    FilteredInvoice.createdon AS sort_date,
    FilteredInvoice.duedate,
    FilteredInvoice.invoicenumber,
    FilteredInvoice.statecodename, 
    FilteredInvoice.totalamount_base,
    FilteredMag_Payment.mag_paymentdate,
    FilteredMag_Payment.mag_amount_base,
    GETDATE() AS Today
FROM    FilteredInvoice 
LEFT OUTER JOIN    FilteredAccount ON FilteredInvoice.accountid = FilteredAccount.accountid 
JOIN    FilteredMag_Payment ON FilteredInvoice.invoiceid = FilteredMag_Payment.mag_invoiceid
WHERE    (FilteredInvoice.statecodename <> 'Canceled')
ORDER BY 3
