查询表达式中的语法错误（缺少运算符）

Question

我在 SQL 中写了一个查询，想在 Microsoft Access 2010 中使用它。我做了大部分必要的翻译，但好像漏掉了一个。但是，我找不到错误是什么。谁能找到错误？

SELECT dbo_job.item, sub2.item AS NewCheck
FROM dbo_job 
LEFT JOIN (
    SELECT dbo_job.item
    FROM dbo_job 
    WHERE dbo_job.job_date<=#7/13/2015# AND dbo_job.job_date>=#6/22/2015#
    GROUP BY dbo_job.item) 
AS sub ON sub.item=dbo_job.item
LEFT JOIN (
    SELECT dbo_job.item
    FROM dbo_job
    WHERE dbo_job.job_date<#7/13/2015#
    GROUP BY dbo_job.item)
AS sub2 ON sub2.item=dbo_job.item
WHERE dbo_job.job_date=#7/20/2015# AND sub.item IS NULL
GROUP BY dbo_job.item, sub2.item

Answer 1

MS Access 要求在联接周围加上额外的括号，因此这可能有效：

SELECT dbo_job.item, sub2.item AS NewCheck
FROM (dbo_job LEFT JOIN
      (SELECT dbo_job.item
       FROM dbo_job 
       WHERE dbo_job.job_date<=#7/13/2015# AND dbo_job.job_date>=#6/22/2015#
       GROUP BY dbo_job.item
      ) AS sub
      ON sub.item = dbo_job.item
     ) LEFT JOIN
     (SELECT dbo_job.item
      FROM dbo_job
      WHERE dbo_job.job_date<#7/13/2015#
      GROUP BY dbo_job.item
     ) AS sub2
     ON sub2.item = dbo_job.item
WHERE dbo_job.job_date = #7/20/2015# AND sub.item IS NULL
GROUP BY dbo_job.item, sub2.item;
