Answer 1

試試這個也許有幫助，

SELECT COUNT(Name) AS total, id, Name 
FROM table_name 
GROUP BY Name 
ORDER BY COUNT(Name) DESC; 

Answer 2

SELECT @rownum:=@rownum+1 AS ID, 
     NameList.iName 
FROM 
     (SELECT DISTINCT iName, COUNT(iName) AS iCount 
     FROM people 
     GROUP BY iName 
     ORDER BY iCount DESC) NameList, 
     (SELECT @rownum:=0) r 

改變這個子查詢

 (SELECT DISTINCT iName, COUNT(iName) AS iCount 
     FROM people 
     GROUP BY iName 
     ORDER BY iCount DESC) 

到名單列表中。

入住這

SELECT id, Name FROM user 
GROUP BY Name 
ORDER BY COUNT(Name) DESC;
