To view an object embedded within a document in MongoDB, you can use the find() method along with dot notation to access the embedded object.


Here's an example:

  1. Connect to your MongoDB database and select the appropriate collection.
  2. Use the find() method to retrieve the document containing the embedded object. For example, to find a document with a specific _id:
1
db.collection_name.find({_id: ObjectId("document_id")})


  1. Use dot notation to access the embedded object within the document. For example, if the embedded object is called "subdocument":
1
db.collection_name.find({_id: ObjectId("document_id")}).subdocument


  1. You can also use dot notation to access specific fields within the embedded object. For example, if the embedded object has a field called "field_name":
1
db.collection_name.find({_id: ObjectId("document_id")}).subdocument.field_name


By following these steps, you can easily view an object embedded within a document in MongoDB.
