MongoDB CreateComplexCollection

Main Page >> MongoDB >>MongoDB Workbook >> Create Complex Collection

Create a Collection

This time we will create a collection in advance and add some nested documents to it.

Check what collections you have already:

show collection

Now create a new one called deptCollection and set some options:

db.createCollection('deptCollection', {max: 20})

In this case we are going to limit our collection to hold a maximum of 20 documents.

This command should return:

 db.createCollection('deptCollection', {max: 20})
 { "ok" : 1 }

To check this has been created:

show collections

Next Step

Inserting data into the collection
