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

Step 1: See all your databases:

show dbs

Step 2: Select the database

use your_database_name

Step 3: Show the collections

show collections

This will list all the collections in your selected database.

Step 4: See all the data

db.collection_name.find() 

or

db.collection_name.find().pretty()

Answer 2

This way:

db.collection_name.find().toArray().then(...function...)

Answer 3

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

show dbs
use <db name>
show collections

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

db.collectionName.find()

More info here on the MongoDB Quick Reference Guide.

Answer 4

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
}

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

Answer 5

This will do:

db.getCollectionNames().forEach(c => {
    db[c].find().forEach(d => {
        print(c); 
        printjson(d)
    })
})
