Android FQL查询，仅获取具有生日的记录。

我只想从fb获取那些指定了生日的记录，我不想要空记录。我有以下疑问：

String fqlQuery = "{" +
                        "'friends':'SELECT uid2 FROM friend WHERE uid1 = me()'," +
                        "'friendinfo':'SELECT uid, name, pic_square, birthday FROM user WHERE uid IN" +
                        "(SELECT uid2 FROM #friends)'," + 
                        "}";

它可以获取所有内容，我尝试了以下方法：

String fqlQuery = "{" +
                        "'friends':'SELECT uid2 FROM friend WHERE uid1 = me()'," +
                        "'friendinfo':'SELECT uid, name, pic_square, birthday FROM user WHERE uid IN" +
                        "(SELECT uid2 FROM #friends)'," + "AND birthday != null"+
                        "}";

它不会给我任何结果，正确的方法是什么

在FQL中，只需使用

和something

检查

something

是否为空

以下是已更正的FQL查询：

{
'friends':'SELECT uid2 FROM friend WHERE uid1 = me()',
'friendinfo':'SELECT uid, name, pic_square, birthday FROM user 
               WHERE uid IN(SELECT uid2 FROM #friends) 
                 AND birthday'
}

Java代码：

String fqlQuery = "{" +
                        "'friends':'SELECT uid2 FROM friend WHERE uid1 = me()'," +
                        "'friendinfo':'SELECT uid, name, pic_square, birthday FROM user WHERE uid IN" +
                        "(SELECT uid2 FROM #friends) AND birthday'"+
                  "}";

还有最后一个问题，我可以获取电话号码和电子邮件等私人信息吗？您无法获取电话号码，但可以通过

电子邮件

字段检索电子邮件。非常感谢，伙计，编码快乐：）
