MongoDB sort

MongoDB sort() method

In MongoDB, the data is sorted using the sort() method, which specifies the sorted fields by parameters and uses 1 and -1 to specify the sort, where 1 is in ascending order and -1 is used for descending ordering.

Grammar

The basic syntax of the sort() method is as follows:

>db.COLLECTION_NAME.find().sort({KEY:1})

Instance

The data in the col collection is as follows:

{ "_id" : ObjectId(5983548781331adf45ec5), "title":"MongoDB Overview"}
{ "_id" : ObjectId(5983548781331adf45ec6), "title":"NoSQL Overview"}
{ "_id" : ObjectId(5983548781331adf45ec7), "title":"Tutorials Point Overview"}

The following example shows the data in the col collection in descending order of the field title:

>db.mycol.find({},{"title":1,_id:0}).sort({"title":-1})
{"title":"Tutorials Point Overview"}
{"title":"NoSQL Overview"}
{"title":"MongoDB Overview"}
>

Note: If you do not specify how the sort() method is sorted, the default is in ascending order of the document.
