Mysql 以分钟计数

我正在检查一些住房数据，想要一份显示最少的邮政编码列表以及返回的计数值（都是相同的）。但是，当我运行下面的查询时，我只得到了答案，而没有得到相关的邮政编码（通过检查，我知道有多个邮政编码具有相同的最小值）。我确实意识到这是由

groupby

函数造成的，该函数有效地按最小值“分组”代码，但我不确定如何获得具有相关最小值的所有zipcode的列表

SELECT MIN(counted)
FROM (SELECT zipcode, count(*) AS counted
  FROM housingprices
  GROUP BY zipcode)
AS COUNTS

我认为你似乎想要：

SELECT zipcode, count(*) AS counted
FROM housingprices
GROUP BY zipcode
HAVING count(*) = (SELECT MIN(counted)
                   FROM (SELECT count(*) AS counted
                         FROM housingprices
                         GROUP BY zipcode)
                  );

您是否尝试过

SELECT MIN（counted），zipcode

我会尝试。好的，这不起作用，因为它返回最小zipcode值和最小计数。不完全是我想要的。你是否尝试过

选择MIN（计数），zipcode

我会尝试。好的，这不起作用，因为它返回最小zipcode值和最小计数。不完全是我想要的。
