Access 2007中的子查询问题

Question

我有一个使用Access 2007的项目，但正在努力编写简单的子查询。我正在尝试从记录一定比率后的下6个事件的表中获得结果。

我希望以下代码在访问中有效：

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];

我在下面收到错误消息。NB 6F Full Form是我写的查询，我正在尝试在子查询中使用它。

查询表达式中的语法错误'[runner name] in(从6f完整表单中选择[runner name]，其中[比率]> 9

Answer 1

您当前的SQL代码的问题是，必须用方括号包含包含空格或保留单词的字段/表/查询名称 - 因此，

from 6F Full Form WHERE

应该写：

from [6F Full Form] WHERE

您在order by子句中也有潜在的错字：

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

---

值得补充的是，您也可以使用加入，例如：

来实现此目标。

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]

Answer 2

尝试以下：

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