我使用了 FQL 查询:
SELECT uid FROM page_fan WHERE page_id = <page_id>
它返回给我这个错误:
{
"error": {
"message": "Your statement is not indexable. The WHERE clause must contain an indexable column. Such columns are marked with * in the tables linked from http://developers.facebook.com/docs/reference/fql ",
"type": "NoIndexFunctionException",
"code": 604
}
}
在这个网站上:http: //developers.facebook.com/docs/reference/fql/page_fan 我使用的所有列都被索引了。
我究竟做错了什么?
