更新中的SQL选择查询

我正在尝试修复此查询：

我有一个更新查询

UPDATE controll_SZHEAD14 
LEFT JOIN [outgoing] ON controll_SZHEAD14.sa_code = [outgoing].Account 
SET [outgoing].Account = controll_SZHEAD14.sa_code, [outgoing].Buyer = controll_SZHEAD14.sa_buyername, [outgoing].startdate = controll_SZHEAD14.sa_date, [outgoing].Finance = controll_SZHEAD14.sa_tedat, [outgoing].maxdate = controll_SZHEAD14.sa_esdat, [outgoing].[25alap] = controll_SZHEAD14.sa_summary
WHERE (((controll_SZHEAD14.sa_code)>"BA14/01997"));

因此，如果我运行上面的查询，则会刷新我的数据，但仅从BA14/01997到现在。所以在本例中，这将刷新66行。（受影响的66排）

我有一个简单的选择SQL：

SELECT TOP 1 Account FROM [outgoing] ORDER BY Account DESC;

如果我在上面运行这个，我得到了最后一个帐户，在这个例子中：BA14/01997

所以我想把这两个查询“更新+选择”放在一起

UPDATE controll_SZHEAD14 
LEFT JOIN [outgoing] ON controll_SZHEAD14.sa_code = [outgoing].Account 
SET [outgoing].Account = controll_SZHEAD14.sa_code, [outgoing].Buyer = controll_SZHEAD14.sa_buyername, [outgoing].startdate = controll_SZHEAD14.sa_date, [outgoing].Finance = controll_SZHEAD14.sa_tedat, [outgoing].maxdate = controll_SZHEAD14.sa_esdat, [outgoing].[25alap] = controll_SZHEAD14.sa_summary
WHERE (((controll_SZHEAD14.sa_code)>"SELECT TOP 1 Account FROM [outgoing] GROUP BY Account DESC;")); 

上述查询无法正常工作。当我运行时，我得到了受影响的0行，但我希望与第一个更新查询相同

---

知道如何解决这个问题吗？

将SELECT语句括在（）括号中

UPDATE controll_SZHEAD14 
LEFT JOIN [outgoing] 
ON controll_SZHEAD14.sa_code = [outgoing].Account 
SET [outgoing].Account = controll_SZHEAD14.sa_code, 
    [outgoing].Buyer = controll_SZHEAD14.sa_buyername, 
    [outgoing].startdate = controll_SZHEAD14.sa_date, 
    [outgoing].Finance = controll_SZHEAD14.sa_tedat, 
    [outgoing].maxdate = controll_SZHEAD14.sa_esdat, 
    [outgoing].[25alap] = controll_SZHEAD14.sa_summary 
WHERE controll_SZHEAD14.sa_code > (
                                    SELECT TOP 1 Account 
                                    FROM [outgoing] 
                                    ORDER BY Account DESC
                                  );

您可以使用

（从[outgoing]中选择MIN（Account））

这样您就不会获取所有记录，对它们进行排序，只返回一个结果。
