Question

我试图让所有包含某个字符串的域都无济于事。

我试过了

fql?q=SELECT url, id, type, site FROM object_url WHERE strpos(url,'a') >=0

并得到：

{
  "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
  }
}

我试过了

fql?q=SELECT domain_name FROM domain WHERE strpos(domain_name,'a') >=0

我得到：

{
  "error": {
    "message": "You must specify a domain_id or a domain_name", 
    "type": "NoIndexFunctionException", 
    "code": 604
  }
}

在图形 api 中，没有搜索类型域或仅 url 页面的选项。我需要从 FB 获取域名

首先我应该查询哪个表域或object_url？
