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

To show all contents from all collections in MongoDB you can use the below-mentioned code:-

var collections = db.getCollectionNames(); 

for(var i = 0; i< collections.length; i++){ 

print('Collection: ' + collections[i]); db.getCollection(collections[i]).find().forEach(printjson)

}

This script might get what you want. It prints the name of each collection and then prints its elements in json. 

Answer 2

Once you are in the terminal/command line, access the database/collection you want to use as follows:

show dbs

use <db name>

show collections

After that choose your collection and type the following command to see all the contents of that collection:

db.collectionName.find()
