mysql - 带有最小值和最大值的 sql 语句

Question

我需要一起使用 min 和 max 编写一个语句。

SELECT companyname  FROM companies JOIN stocklist 
USING (companyid) where price =some(
( select max(price) from stocklist) , ( select min(price) from stocklist) ) ;

我需要获得最低和最高价值的公司名称，但这不起作用（因为最后一行）出了什么问题，我应该怎么做？

更新：

select companyname from stockList join companies using (companyid) WHERE price IN (select min(price) from stocklist) ;

这对我有用，但只有一个操作数，我怎样才能得到两个？

Answer 1

I don't like the idea of having two subqueries in an IN clause. Here is another way with the join being made explicit:

SELECT companyname 
FROM companies c JOIN
     stocklist s
     c.companyid = s.companyid join
     (select min(price) as minprice, max(price) as maxprice
      from stocklist
     ) sm
     on s.price = minprice or s.price = maxprice

Answer 2

尝试这个：

SELECT companyname  FROM companies c
INNER JOIN stocklist s
ON c.companyid = s.companyid
WHERE price IN
((SELECT MAX(price) FROM stocklist ), 
 (SELECT MIN(price) FROM stocklist ))
