FQL profile.pic_square 和 thread.subject

Question

是否可以使用 FQL 在 Facebook API 中连接两个表？

SQL 风格的经典方法不起作用。

希望你能帮忙:)

正如文档所说，

Facebook Query Language, or FQL, enables you to use a SQL-style interface to query the data exposed by the Graph API. It provides for some advanced features not available in the Graph API, including batching multiple queries into a single call.
You can execute FQL queries by fetching https://api.facebook.com/method/fql.query?query=QUERY. You can specify a response format as either XML or JSON with the format query parameter.
Queries are of the form SELECT [fields] FROM [table] WHERE [conditions]. Unlike SQL, the FQL FROM clause can contain only a single table. You can use the IN keyword in SELECT or WHERE clauses to do subqueries, but the subqueries cannot reference variables in the outer query's scope. Your query must also be indexable, meaning that it queries properties that are marked as indexable in the documentation below.
FQL can handle simple math, basic boolean operators, AND or NOT logical operators, and ORDER BY and LIMIT clauses.
For any query that takes a uid, you can pass me() to return the logged-in user. For example:
SELECT name FROM user WHERE uid = me() 
Other functions that are available are now(), strlen(), substr() and strpos().
Here's an example of a subquery that fetches all user information for the active user and friends:
SELECT uid, name, pic_square FROM user WHERE uid = me()
OR uid IN (SELECT uid2 FROM friend WHERE uid1 = me())

他们没有提到加入。所以我认为你不能这样做。
