fql查詢一次 - facebook api

Question

$status = $facebook->api_client->fql_query("SELECT message,time FROM 
status WHERE uid in (SELECT uid2 FROM friend WHERE uid1=".$user.")"); 

echo "<pre>"; 
print_r($status); 
echo "</pre>"; 

上面的查詢返回所有狀態，我只想要最後2個狀態消息。我只能用fql來做。誰能告訴我它是如何完成的？

Answer 1

您可以指定LIMIT 2以僅返回兩條記錄。

$status = $facebook->api_client->fql_query("SELECT message,time FROM 
status WHERE uid in (SELECT uid2 FROM friend WHERE uid1=".$user.") LIMIT 2"); 

echo "<pre>"; 
print_r($status); 
echo "</pre>"; 

根據你想達到什麼，你可能還需要添加一個ORDER BY。
