如何執行此查詢以選擇具有最高編號的N行col :)

Question

假設我有一個包含三列的表：ID，名稱和用戶。

我想選擇用戶數量最多的3行，我希望行按名稱升序排序。我如何實現這一目標？

我用

select Name from TABLE where ID IN (select ID from Tablesorder by Users desc limit 3) 

但在/ ANY不被支持。任何其他方式？ 謝謝

Answer 1

當允許子查詢時，您可以使用它。 它爲列用戶提取最高值的3條記錄。這3個結果將在外部查詢中進行排序。

select Name from 
(
    select Name 
    from Tables 
    order by Users desc 
    limit 3 
) as temp 
ORDER BY Name ASC

在MySQL：

SELECT id, name, users 
FROM (SELECT id,name,users FROM tablename ORDER BY users DESC LIMIT 3) as a 
ORDER BY name; 

在SQL Server

SELECT id, name, users 
FROM (SELECT TOP 3 id,name,users FROM tablename ORDER BY users DESC) as a 
ORDER BY name; 

在Oracle

SELECT id, name, users 
FROM (SELECT id,name,users FROM tablename ORDER BY users DESC) as a 
WHERE ROWNUM<=3 
ORDER BY name;
