具有-SQL的SSMS计数

我试图计算数据库中的部门数量，每个部门有6名员工

我已经在下面编写了查询，但它返回了包含6名员工的部门的行

但我想要的是每个部门有6名员工的总行数

有人知道我如何修改这个查询来给我一个总数吗

您可以使用另一个

count

语句包装查询，以统计内部查询返回的部门数：

select COUNT(*) from
(
    select Department as cnt
    from HumanResources.vEmployeeDepartment
    GROUP BY Department
    HAVING count(Department) = 6  
) as t

select COUNT(*) from
(
    select Department as cnt
    from HumanResources.vEmployeeDepartment
    GROUP BY Department
    HAVING count(Department) = 6  
) as t
