查询表达式中的语法错误（缺少运算符）

Question

我在SQL中编写了一个查询，并希望在Microsoft Access 2010中使用它。我完成了大部分必要的翻译，但似乎我错过了一个。但是，我找不到错误是什么。谁能找到错误？

Hash = 1210600964 * 31 + -837896230

MS Access需要在连接周围添加额外的括号，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;
