suppose I have a json object as below:

{
  "_id" : some mongo generated id,
  "name" : "NEW NODE",
  "example_list" : [{
     "_id" : "1.3.12.2.1107.5.99.3.30000008061114424970500000589",
     "Index" : 0,
     "Type" : "Study"
     }, {
      "_id" : "cc7e1966-e885-4a9a-8077-c3489118938d",
      "Index" : 1,
      "Type" : "TestCase"
    }]
}

now I want to delete "Type" from "example_list" in mongo shell.

Is there any way to do it in mongo shell?

I have found some scripts but its not working on mongo shell I am more inclined on doing this on mongo shell but other ways are also fine.

How many records you want to update? Is there any specific condition you need to check before removing the field? – Shrabanee Jun 20 '16 at 10:15
maybe 10-20 records. No there is no check for removing the field. I just have to remove it. – Asit Kumar Singh Jun 20 '16 at 10:17
