Question

我有一个FQL查询返回对帖子发表评论的人员列表： -

SELECT time，fromid，likes，post_id_cursor from comment where post_id ='331288023558058_592220760798115'ORDDER BY time DESC LIMIT 5000

我想要做的是在此查询中包含另一个查询，以返回留下评论的人的更多详细信息

SELECT sex，first_name，middle_name，last_name，username，locale，profile_url，pic_square_with_logo FROM user WHERE uid = {fromid of person leaving comment}

是否可以组合查询以便在单个查询中获取所有数据？有什么想法吗？

Answer 1

使用多个查询

commentquery =“SELECT time，fromid，likes，post_id_cursor from comment where post_id ='331288023558058_592220760798115'ORDDER BY time DESC LIMIT 5000”

userquery = SELECT sex，first_name，middle_name，last_name，username，locale，profile_url，pic_square_with_logo FROM user WHERE uid =（SELECT fromid FROM #commentquery）

要使用多个FQL查询，您需要对数组中的查询进行json_encode。对于/ fql？q =参数

所以要指定：

$queries = [];
$queries['comments'] = "SELECT time, fromid... ";
$queries['users'] = "SELECT sex, ... WHERE uid IN (SELECT fromid FROM #comments)";

$fql = json_encode($queries);
// then using curl or whatever 
// (multiqueries don't work with PHP sdk's $facebook->api() i believe)
GET http://graph.facebook.com/fql?q=$fql

Answer 2

使用多重查询

graph.facebook.com/fql?q={"query1":"SELECT time, fromid, likes, post_id_cursor from comment where post_id = '331288023558058_592220760798115' ORDER BY time DESC LIMIT 5000","query2":"SELECT sex, first_name, middle_name, last_name, username, locale, profile_url, pic_square_with_logo FROM user WHERE uid IN (SELECT fromid FROM #query1)"}

Answer 3

您可以在此处找到答案：fql join; can i join two tables with FQL?

您想要使用多个查询加入这两个查询。希望有所帮助。

如何使用来自第一个查询的userid在查询中创建FQL查询？
