MongoDB CRUD Operations

CREATE DATABASE IN mongoDB

MongoDB use DATABASE_NAME is used to create database. The command will create a new database if it doesn't exist, otherwise it will return the existing database.

Syntax

syntax of create database is as follows - e.g. : use DataBaseName

Like :- use TestDB

Note :- CURD means create, read, update, and delete

1 :- CREATE COLLECTION

MongoDB createCollection(name, options) is used to create collection.

e.g :- db.createCollection("Student", { size: 2147483648 } )

2 :- CREATE OPERATIONS

syntax :- 1) db.collection.insertOne()

2) db.collection.insertMany()

Note:- (INSERT Data into Collection)

e.g :-1--) if insert one record

db.Student.insertOne( { name: "mohan", class: "BCA", rollno :5} );

e.g :- 2--) if insert multiple record at one time

db.Student.insertMany( [

{ name: "mohan", class: "BCA", rollno :5},

{ name: "sohan", class: "MBA", rollno :15},

{ name: "ram", class: "BBA", rollno :10},

{ name: "shyam", class: "MCA", rollno :25},

] );

3 :- READ OPERATIONS

syntax : db.collection.find(query, projection)

e.g :- db.Student.find()

e.g :-1) db.Student.find({ name: "shyam" })

e.g :-2) db.Student.find( { rollno : 5 } )

4 :- UPDATE OPERATIONS

syntax :- db.collection.update(selectQuery, udateQuery)

e.g :-1 )

db.Student.update({'name':'shyam'},{$set:{'name':'shyam kumar'}})

db.Student.update({'id':'2'},{$set:{'name':'Mohan kumar'}})

e.g :-2)

Note:- update class where rollno is greater than 10

db.Student.updateMany(

{ rollno : { $gt: 10 } },

{ $set: { "class" : 'PHD'} }

);

5 :- DELETE OPERATIONS

syntax :-1 ) db.collection.deleteOne()

:-2 ) db.collection.deleteMany()

e.g:- 1)

db.Student.deleteOne( { rollno : 4 } )
