Access 2007 中的子查询问题

Question

我有一个使用 Access 2007 的项目，但正在努力编写一个简单的子查询。在记录了特定比率后，我正在尝试从接下来的 6 次 table 中获取结果。

我希望以下代码可以在 Access 中运行：

SELECT [runner name], [race ID], [race date], [placing], [class]
FROM runners
WHERE [runner name] IN
                 (SELECT [runner name] from 6F Full Form WHERE [ratio] >9       
ORDER BY [runner name], [race ID], [date], [placing], [class];

我收到以下错误消息。注意 6F Full Form 是我编写的查询，我正尝试在子查询中使用它。

Syntax error in query expression '[runner name] IN (SELECT [runner name] from 6F Full Form WHERE [ratio] >9

Answer 1

试试这个：

 (SELECT [runner name] 
 FROM [6F Full Form] 
 WHERE [ratio] >9       
 ORDER BY [runner name], [race ID], [date], [placing], [class]);

Answer 2

您当前 SQL 代码的问题是 field/table/query 包含空格的名称或 reserved words 必须用方括号括起来 - 因此

from 6F Full Form WHERE

应该写成：

from [6F Full Form] WHERE

您的 order by 条款中也可能存在错字：

SELECT ..., [race date], ...
...
ORDER BY ..., [date], ...;
                 ^--------------- Should this be [race date]?

值得补充的是，您也可以使用联接来实现此目的，例如：

select
    r.[runner name],
    r.[race id],
    r.[race date],
    r.[placing],
    r.[class]
from
    runners r inner join
    (select distinct f.[runner name] from [6f full form] f where f.[ratio] > 9) q 
    on r.[runner name] = q.[runner name]
order by
    r.[runner name],
    r.[race id],
    r.[race date],
    r.[placing],
    r.[class]
