JavaMadeSoEasy.com (JMSE): find document where _id=1 and firstName='xyz' in mongoDB

Contents of page >

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 }
