Question

注意（deptid = 2,3）或（deptid = 1且总和（总费用）= 0）

select * 
into employee1 
from employee2 
where empid in (select distinct empid 
                from employee3 e3 
                join employee2 e2 on e3.empid = e2.empid
                where e3.deptid in (2,3) 
                   or (e3.deptid = 1 
                group by empid, cost  
                having sum(e2.cost) = 0))

Answer 1

我会给你一个很大的猜测。这些都是我的问题。

该查询可能会返回多个结果，因此无法使用INTO employee1
employee3看起来应该是depatment table

我创建了一个cte来首先计算每个员工的成本。然后验证部门。

WITH ecost as (
    select e.empid, SUM(e.cost) as cost
    from employee2 e
    group by e.empid
)
select e.empid
from ecost e
inner join employee3 d
       on e.empid = d.empid           
where 
   d.deptid  in (2,3)
or (d.deptid = 1 and e.cost = 0)

在SQL Server中分组并具有OR条件
