MongoDB — Insert

Insert One

db.users.insertOne({
  name: "John Doe",
  email: "john@example.com",
  age: 30
})

Insert Many

db.users.insertMany([
  { name: "Jane", email: "jane@example.com", age: 25 },
  { name: "Bob", email: "bob@example.com", age: 35 }
])

Insert with ObjectId

db.users.insertOne({
  _id: ObjectId("507f1f77bcf86cd799439011"),
  name: "John"
})

Insert Result

{
  acknowledged: true,
  insertedIds: {
    "0": ObjectId("...")
  }
}

Ordered vs Unordered

// Ordered (stops on error)
db.users.insertMany([...], { ordered: true })

// Unordered (continues on error)
db.users.insertMany([...], { ordered: false })

Mini Practice

1. Insert single document
2. Insert multiple documents
3. Handle insert errors
4. Use ordered inserts
