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

According to MongoDB db.collection.remove() reference:

justOne

An optional boolean value. To limit the deletion to just one document, set to true. Omit to use the default value of false and delete all documents matching the deletion criteria.

You can set the justOne to true, in order to do it.

Before MongoDB version 2.6:

db.collection.remove(
   ,
   
)

MongoDB version 2.6 or later:

db.collection.remove(
   ,
   {
     justOne: ,
     writeConcern: 
   }
)

Like this: db.collection.remove({"condition": "some condition"}, {justOne: true});.
