Question

大师，

我需要帮助来修复此查询：

我有更新查询。

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，如果我在上面运行此查询，则刷新我的数据，但仅从BA14 / 01997到现在。所以在这个例子中，这将刷新66行。（66排受影响）

我有这个简单的选择sql：
```
SELECT TOP 1 Account FROM [outgoing] ORDER BY Account DESC;
```
如果我在上面运行，我得到了最后一个帐户，在这个例子中：BA14 / 01997

所以我想采取这两个问题＆＃34;更新+选择＆＃34;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;"));

以上qquery无法正常工作。当我运行时，我受到0行的影响，但我希望与第一次更新查询相同。

知道如何解决这个问题吗？

谢谢

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
                                  );

更新中的SQL选择查询
