Try $unset
in a call to update()
.
Like this:
db.collection_name.update({ _id: 1234 }, { $unset : { description : 1} })
And, as vikneshwar commented, if you want to remove one field from all (or multiple) documents you can use updateMany()
like this:
db.collection_name.updateMany({}, { $unset : { description : 1} })
