FIND Example > find document where _id=1

First, Let's create new collection and insert document in it >
> db.employee.insert({_id : 1,  firstName:"ankit"})
> db.employee.insert({_id : 2,  firstName:"ankit", salary : 1000 })
> db.employee.insert({_id : 3,  firstName:"sam", salary : 2000 })
> db.employee.insert({_id : 4,  firstName:"neh", salary : 3000 })
First line above will create table (or collection) (if table already exists it will insert documents in it).


1) FIND Example > find document where _id=1 >
> db.employee.find({_id:1})
Output>
{ "_id" : 1, "firstName" : "ankit" }


2) FIND Example > find document where firstName= "sam" >
> db.employee.find({firstName:"sam"})
Output>
{ "_id" : 3, "firstName" : "sam", "salary" : 2000 }
