如何獲取用戶在mysql中的排名位置？

Question

你好我是試圖獲得與此代碼的位置：

$sql = mysql_query("SELECT @rownum:=@rownum+1 AS posicao, nome, pontos FROM ranking u, (SELECT @rownum:=0) r ORDER BY pontos DESC"); 

它的工作原理，但我希望某個特定用戶的位置，我用這個代碼：

$sql = mysql_query("SELECT @rownum:=@rownum+1 AS posicao, nome, pontos FROM ranking u, (SELECT @rownum:=0) r WHERE pontos=100 ORDER BY pontos DESC"); 

但只返回一個記錄，我無法得到這個位置，因爲它總是1！

有人幫我嗎？謝謝

嘗試

SELECT * FROM 
(SELECT @rownum:=@rownum+1 AS posicao, nome, pontos 
FROM ranking u, (SELECT @rownum:=0) r 
ORDER BY pontos DESC 
) as a 
WHERE pontos = 100 
;
