retriving所有行与最大值

Question

我有这样的查询：

SELECT state AS ls,count(*) AS total, max(sales) AS ye FROM TABLE 
GROUP BY state 

然后我得到以下结果：

A total ye 
---------- 
a 22 23 
b 23 23 
c 24 21 
d 25 21 

但我想显示具有ye最大值仅为状态，即：

A total ye 
---------- 
a 22 23 
b 23 23 

Answer 1

select state as ls,count(*) as total ,max(sales) as ye from table  
where sales = (select max(sales) from table) 
group by state 

Answer 2

您可以使用此HAVING条款，它类似于WHERE只有在检索完所有数据后才执行它。您可以通过像组后指定它：

select state as ls,count(*) as total ,max(sales) as ye from table  
group by state 
having count(*) = max(sales) 

Answer 3

尝试此查询：

select * from (select state as ls,count(*) as total ,max(sales) as ye from table  
group by state)temp HAVING max(ye); 

Answer 4

尝试：

select state as ls,count(*) as total, max(sales) as ye from table  
group by state 
having max(sales) = (select max(sales) from table)
