How to connect to my MongoDB table by command line?

In order to connect to my table by command line, you need to use db command

db.yourCollectionName.find();

Let’s say we have a database “sample” with some collections. First check the current database

> use sample;
switched to db sample
> db;
Sample
Now we have reached the database sample. The database “sample” is having the following collections:
> show collections;

This will produce the following output

Here is the correct way of connecting to a table i.e. collection. You need to use db command. Following is the query

> db.userInformation.find();

This will produce the following output

{ "_id" : ObjectId("5c6a765964f3d70fcc9147f5"), "Name" : "John", "Age" : 30, "isStudent" : false, "Subjects" : [ "Introduction to java", "Introduction to MongoDB" ] }
