Create collection(table) and insert document(rows) in Mongodb
Create the table and insert data into the MongoDB. Following are the steps for MongoDB:
1. Check the db which is connected.
db
2. Connect with mydb database
use mydb
3. Create two documents named j and k by using the following sequence of javascript
j = {name:"RAM"}
k = {address:"delhi"}
i = {x:3}
4. Insert the j, k and i into the collection name employee
db.employee.insert(j)
db.employee.insert(k)
db.employee.insert(i)
5. Check the collection exists
show collections
6. confirm the document insert into the collection
db.employee.find()
Example
-- Switch to the DB
> use mydb
switched to db mydb
-- Show all db present
> show dbs
admin (empty)
local 0.078GB
test (empty)
-- Assigned value
> j={name:"RAM"}
{ "name" : "RAM" }
> k={address:"Delhi"}
{ "address" : "Delhi" }
> i={empno:10}
{ "empno" : 10 }
-- Insert data into collection
> db.employee.insert(j)
WriteResult({ "nInserted" : 1 })
> db.employee.insert(k)
WriteResult({ "nInserted" : 1 })
> db.employee.insert(i)
WriteResult({ "nInserted" : 1 })
--Check collection present in DB
> show collections
employee
system.indexes
--Run Select query for fetch inserted data
> db.employee.find()
{ "_id" : ObjectId("540eb24efbf4b1a1447adde9"), "name" : "RAM" }
{ "_id" : ObjectId("540eb25ffbf4b1a1447addea"), "address" : "Delhi" }
{ "_id" : ObjectId("540eb267fbf4b1a1447addeb"), "empno" : 10 }
--Check databases
> show dbs
admin (empty)
local 0.078GB
mydb 0.078GB
test (empty)
