保持在MySQL SQL命令

Question

組

後，我有一個SQL

select site_id,count from tags where match (tag) against ('statistici' in boolean mode) ORDER BY count DESC; 

+---------+-------+ 
| site_id | count | 
+---------+-------+ 
|  9 | 1300 | 
|  13 | 1200 | 
|  9 | 1100 | 
|  13 | 1000 | 
|  9 | 900 | 
|  13 | 800 | 
|  13 | 800 | 
+---------+-------+ 

什麼，我需要的是讓不同的SITE_ID。 但是當我通過語句中使用一組由數的順序沒有保持

select site_id,count from tags where match (tag) against ('statistici' in boolean mode) GROUP by site_id ORDER BY count DESC; 

+---------+-------+ 
| site_id | count | 
+---------+-------+ 
|  13 | 1000 | 
|  9 | 900 | 
+---------+-------+ 

我應該怎麼辦？

Answer 1

您正在訂購ORDER BY count DESC，結果以最高的優先次序排列。

如果您偏​​好最低的數字，請更改爲ORDER BY count ACS。

編輯：基於您的評論，或許這更像是你想達到什麼目的：

select site_id 
,  max(count) as TopCount 
from tags 
where match (tag) against ('statistici' in boolean mode) 
group by 
     site_id 
order by 
     TopCount DESC 

這將選擇每個站點的最高次數，第一個地方的最高計數。
