mysql - 如何在 SQL 中获取所选计数的最小值

Question

我正在尝试从精选的计数中获取最小值。

SELECT selectSumOfToyCount.kidsFname, MIN(selectSumOfToyCount.sumToyCount)
(SELECT kidFName,  SUM(kids_to_toys.toyCount) sumToyCount
    FROM kids
        NATURAL JOIN kids_to_toys
        NATURAL JOIN toys
    GROUP BY kidFName
) selectSumOfToyCount
GROUP BY selectSumOfToyCount.kidsFname

() 内的 select 语句可以工作，但它总是从外部语句中给我一个错误。 我假设我的别名正确吗？

selectSumOfToyCount 用于内部 () selected 语句， sumToyCount 用于求和。

Answer 1

只需按 desc 排序并获取顶行即可。

select * from (
 SELECT kidFName,  SUM(kids_to_toys.toyCount) sumToyCount
 FROM kids
    NATURAL JOIN kids_to_toys
    NATURAL JOIN toys
GROUP BY kidFName
)  order by sumToyCount desc limit 0,1
