我正在使用测试数据库Advetureworks,我希望得到结果中第二高的数,但我没有得到它.
我必须对以下查询进行哪些更改才能获得所需的结果？
select pa.City,psp.Name,COUNT(he.EmployeeID) as emp_count
from HumanResources.EmployeeAddress hea
join HumanResources.Employee he on he.EmployeeID=hea.EmployeeID
join Person.Contact pc on pc.ContactID=he.ContactID
join Person.Address pa on pa.AddressID=hea.AddressID
join Person.StateProvince psp on psp.StateProvinceID=pa.StateProvinceID
where COUNT(he.EmployeeID) < (select max(count(he.employeeid)) from HumanResources.Employee)
group by pa.City,psp.Name
