DocumentDb无法处理列名中的连字符( - )

Question

我将以下XML保存到DocumentDB:

<DocumentDbTest_Countries> 
  <country>C25103657983</country> 
  <language>C25103657983</language> 
  <countryCode>383388823</countryCode>
  <version>2015-08-25T08:36:59:982.3552</version>
  <integrity>
     <hash-algorithm>sha1</hash-algorithm>
     <hash /> 
  </integrity>
  <context-info> 
     <created-by>unittestuser</created-by> 
     <created-on>2015/08/25 08:36:59</created-on> 
     <created-time-zone>UTC</created-time-zone> 
     <modified-by>unittestuser</modified-by>
     <modified-on>2015/08/25 08:36:59</modified-on> 
     <modified-time-zone>UTC</modified-time-zone>
  </context-info>
</DocumentDbTest_Countries>

哪个可以保存到DocumentDB中,如下所示:

{
"DocumentDbTest_Countries": {
"integrity": {
   "hash-algorithm": "sha1",
   "hash": ""
  },
"context-info": {
  "created-by": "unittestuser",
  "created-on": "2015/08/25 08:36:59",
  "created-time-zone": "UTC",
  "modified-by": "unittestuser",
  "modified-on": "2015/08/25 08:36:59",
  "modified-time-zone": "UTC"
},
"country": "C25103657983",
"language": "C25103657983",
"countryCode": 383388823,
"version": "2015-08-25T08:36:59:982.3552"
},
"id": "f917945d-eaee-4eff-944d-dae366de7be1"
}

正如您所看到的,列名确实在DocumentDB中保存了连字符( - )(显然没有任何类型的错误/异常/警告)但是当我尝试进行查找时,它在查询资源管理器中失败了.似乎没有办法搜索带连字符的列名.这是真的？或者,我错过了什么？有人可以指点我某个关于这个限制的文件吗？

对于使用某些字符(空格,"@"," - "等)或与SQL关键字冲突的字段名称,必须使用带引号的属性访问器语法.所以不要写:

SELECT * FROM c WHERE c.context-info.created-by = "unittestuser"

写:

SELECT * FROM c WHERE c["context-info"]["created-by"] = "unittestuser"
