Remove only one document in MongoDB

Question

when I call

db.collection.remove({\'condition\':\'some condition\'});

This one line will delete all the matching condition documents.

Answer 1

You need to perform two separate queries for this

• take only one item from the matching filters

  var item = db.collection.findOne({'condition':'some condition'})
  

• and delete the item by using the id

   db.collection.remove({_id: item._id});
  

Answer 2

Can't you just run a find first to get the id then a delete when you have the one you want?

Answer 3

db.collection.remove now has a justOne flag

http://docs.mongodb.org/manual/reference/method/db.collection.remove/#db.collection.remove

Answer 4

If there are multiple records and you want to delete only first record, then set justOne parameter in remove() method.

Here, you want to delete only 1. Thus, set "justOne" parameter as 1.

db.collection.remove({'condition':'some condition'},1);

Answer 5

To remove one document from collection use the bellow command

db.collectionname.remove({"_id": ObjectId("5473293d43ecdre56352457f3a")})

Answer 6

Try this one for delete.

db.users.deleteOne({"_id": ObjectId("5473293d43ecdre56352457f3a")});
