Question

我有以下查询

select distinct 
people.id
from people
inner join incident on people.id = incident.peopleid 
where  incident.service =4
AND people.id NOT IN (
select  incident.peopleid
from Incident
where 
incident.service IN =4
AND incident.ServiceInterrupt != 0
)

这给了我所有属于服务的人，他们还没有中断该服务。我想对服务5和6运行此查询，并且这些结果仅采用唯一的人。直到现在，我运行查询3次（每次更改服务）然后我删除重复与excel！还有其他办法吗？

提前致谢

编辑：更具体地说，我希望从结果中排除服务X中仅具有中断服务X的所有人员。这就是为什么我不能在（4,5,6）中使用incident.service来代替incident.service = 4

Answer 1

我认为你可以使用这样的东西;

select distinct 
people.id
from people
inner join incident i1 on people.id = i1.peopleid 
where  i1.service in(4,5,6)
AND people.id NOT IN (
select  i2.peopleid
from Incident i2
where 
i2.service = i1.service
AND i2.ServiceInterrupt != 0
)

Answer 2

试试这个：

select distinct 
people.id
from people
inner join incident on people.id = incident.peopleid 
where  incident.service IN(4,5,6)
AND incident.ServiceInterrupt != 0

不同查询之间的SQL不同值
