Sort () method in MongoDB
To sort documents in MongoDB, you need to use the sort () method . The sort () method takes a Document containing a list of fields with their sort order. To determine the sort order, 1 and -1 are used. 1 is used for ascending order, while -1 is used for descending order.
Syntax
The basic syntax of sort () method is as follows:
> db . COLLECTION_NAME . find (). sort ({ KEY : 1 })
For example
You follow Collection with the name mycol with the following data:
{ "_id" : ObjectId ( 5983548781331adf45ec5 ), "title" : "MongoDB Overview" } { "_id" : ObjectId ( 5983548781331adf45ec6 ), "title" : "NoSQL Overview" } { "_id" : ObjectId ( 5983548781331adf45ec7 ), "title" : "Tutorials Point Overview" }
The following example displays the Document sorted by title in descending order.
> db . mycol . find ({},{ "title" : 1 , _id : 0 }). sort ({ "title" :- 1 }) { "title" : "Tutorials Point Overview" } { "title" : "NoSQL Overview" } { "title" : "MongoDB Overview" } >
Remember if you don't specify the sort order, the sort () method will display the Document in ascending order.
