聚合函数的SQL比较

当我在ACCESS 2007中运行以下sql时

Select Location,
COUNT(ApartmentBuildings) AS
TotalIBuildingsManaged From Apartments
Where COUNT(ApartmentBuildings) > 3
Group By Location Order By
COUNT(ApartmentBuildings) DESC;

我收到以下错误：

在where子句中不能有聚合函数.如何构建此查询以获取所有具有大于3的ApartmentBuildings数量的位置？

解决方法

使用而不是在哪里：

Select Location,COUNT(ApartmentBuildings) AS TotalIBuildingsManaged 
From Apartments 
Group By Location
Having COUNT(ApartmentBuildings) > 3  
Order By COUNT(ApartmentBuildings) DESC;
