MongoDB Show all contents from all collections

Question

Is it possible to show all collections and its contents in MongoDB?

Is the only way to show one by one?

Answer 1

Before writing below queries first get into your cmd or PowerShell

TYPE:
mongo             //To get into MongoDB shell
use       //For Creating or making use of existing db

To List All Collection Names use any one from below options :-

show collections  //output every collection
  OR
show tables
  OR
db.getCollectionNames() //shows all collections as a list

To show all collections content or data use below listed code which had been posted by Bruno_Ferreira.

var collections = db.getCollectionNames();
for(var i = 0; i< collections.length; i++) {    
   print('Collection: ' + collections[i]); // print the name of each collection
   db.getCollection(collections[i]).find().forEach(printjson); //and then print     the json of each of its elements
}
