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.

What If I want to remove only one of any or n-th matching condition?

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});
