I have a mongodb document that is autogenerated that uses dashes in field names.  How do I construct a query or assignment that uses them ?   It doesn't like embedded dashes and I can't figure out how to escape the field names so I can use them as variables in expressions.

 
"Doc" : [
  {
    "field-1" : "alpha",
    "stuff": {
       "more-stuff" :  1,
       "even-more-stuff" : 2,
       "embedded-array" : [ 
          {
            "e-1": 100, 
           "e-2":101
          }
       ]
      } 
  },
  {
     "field-1" : "beta",
     "stuff": {
       "more-stuff" :  3,
       "even-more-stuff" : 4,
       "the-cookie":55
        } 
  }
]

Open in new window


How would I assign x to the field name associated with "The cookie" and then, so It is a better learning experience, create a cursor on "embedded-array" so a jsonprint(EmbeddedArray")  reports the e-1 and e-2 fields and values?

Solved it ... you need to use dot notation

so a field name such as e-1 would be represented by ['e-1']
