Insert Document

• Let’s insert dome documents into the collection mycollection
• db.mycollection.insert({"color":"white","example":"milk"})
• The above command inserts the json document {“color”:”white”,”example”:”milk”} into the collection.
• Let’s insert another one:
• db.mycollection.insert({"color":"blue","example":"sky"})
• Insert more as you see below in the code

training> db.mycollection.insert({"color":"white","example":"milk"})

# DeprecationWarning: Collection.insert() is deprecated. Use insertOne, insertMany, or bulkWrite.

  acknowledged: true,
  insertedIds: { '0': ObjectId('67167ac0ac0fee924e964033') }

# Let's insert another one
training> db.mycollection.insert({"color":"blue","example":"sky"})
{
  acknowledged: true,
  insertedIds: { '0': ObjectId('67167b3eac0fee924e964034') }

}

# Now let's count all the documents
training> db.mycollection.countDocuments()
5

# Let's list all the documents in the collection
training> db.mycollection.find()
