I have a collection:
{
"student_id":"123",
"test": [

{ "date_created": "12/3/2013" }

]
}

I want to unset date_created for all the test object for student_id 123, I placed the query as:
db.students.update(

{ "student_id" : "1234"}

{ "$unset" : { "test.$.date_created" : ""}}), but it doesn't work. Whereas the same query works if I want to "$set" any field.
