一擊式FQL查詢-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，我只想要最后2條狀態消息。 我只能用fql做到。 誰能告訴我它是怎么做的？

Answer 1

您可以指定LIMIT 2僅返回兩個記錄。

$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>"; 

根據您要實現的目標，您可能還需要添加ORDER BY。
