QUESTION
I have created a database called "Cars" and a collection inside it as, "Cars_info". I have inserted 8 documents inside it as follows.
...ANSWER
Answered 2022-Mar-03 at 10:54You need .skip()
and .limit()
.
Take the document by starting index: 2 and with only 1 document, which is the third document.
Update: Thanks and credit to @Wernfried for pointing out, you need .sort()
to guarantee to get the nth of the document. For your scenario, you have to sort by car_id
.
MongoDB does not store documents in a collection in a particular order. When sorting on a field that contains duplicate values, documents containing those values may be returned in any order.
