如何将此mysql查询转换为postgres 9.4

Question

首先，我在两个数据库（MySQL和Postgres）中都有相同的表名，列和数据，我用于MySQL 5.6.24的查询可以使用它

select *,abs(longitudes - -81.4563009)+abs(latitudes-28.11657) as LowestNum 
from zips group by LowestNum limit 1

当我将相同的查询放入postgres 9.4时，我基本上试图获得最近的位置给出纬度和经度我得到一个错误状态

ERROR: column "zips.zip" must appear in the GROUP BY clause or be used in an aggregate function
SQL state: 42803
Character: 8

然后我改变了一切并做了这个

select *, abs(longitudes - -81.3952524)+abs(latitudes-28.4583868) as   
LowestNum from zips group by LowestNum,zips.zip limit 1

我收到此错误

ERROR: column "zips.ziptype" must appear in the GROUP BY clause or be used in an aggregate function
SQL state: 42803
Character: 8

我是postgres的新手但是一直在查看文档并四处搜索，没有任何建议。

这个怎么样：

select *, abs(longitudes - -81.4563009)+abs(latitudes-28.11657) as LowestNum 
from zips 
order by LowestNum ascending 
limit 1

抱歉，我没有PostgreSQL实例来测试它。

order by [..] ascending/descending limit 1是一种避免min和max的常用方法，以及当您拥有多个结果列（group by，加入时）所带来的困难。< / p>
