SQL Server查询不在另一个表中的地方

Question

我有三张桌子:

工作

    JobId
    StartDate
    RehireDate

证件

    PaperworkId
    DocumentName

JobPaperwork

    JobId
    PaperworkId
    Completed

我需要找到没有为其分配具有特定文档名称的文档的任何作业.我不确定如何构造此查询.使用NOT IN不起作用,因为它返回每个作业,因为它正在找到分配给他们的其他文书工作的作业.

这是我开始的:

select j.jobid 
from Job j 
inner join JobPaperwork jp on j.JobId = jp.JobID 
where j.startdate > dateadd(day, -30, getdate()) 
  and j.rehiredate is not null 
  and jp.PaperworkID not in (select paperworkid 
                             from Paperwork 
                             where documentname like '%searchterm%') 

Answer 1

select j.jobid 
from Job j 
inner join JobPaperwork jp on j.JobId = jp.JobID 
where j.startdate > dateadd(day, -30, getdate()) 
and j.rehiredate is not null 
and NOT EXISTS ( select 1 
                 from Paperwork pw 
                 where jp.PaperworkID = pw.paperworkid
                 and pw.documentname like '%searchterm%'
                )
