MongoDB 新增資料

同樣使用 mongo shell 操作，新增單筆使用 insertOne()：

> use test
switched to db test
> db.inventory.insertOne({
...   "item": "notebook1",
...   "qty": 50,
...   "size": {
...     "h": 8.5,
...     "w": 11,
...     "uom": "in"
...   },
...   "status": "A"
... })
{
    "acknowledged" : true,
    "insertedId" : ObjectId("5ea6f2ab40e9db6af06a231a")
}

新增多筆使用 insertMany()：

> db.inventory.insertMany([
...   {
...     "item": "notebook2",
...     "qty": 10
...   },
...   {
...     "item": "notebook3",
...     "qty": 13
...   }
... ])
{
 "acknowledged" : true,
 "insertedIds" : [
  ObjectId("5ea6f53240e9db6af06a231b"),
  ObjectId("5ea6f53240e9db6af06a231c")
 ]
}

尋找剛剛新增的兩筆：

> db.inventory.find({item:/^notebook[23]/}).pretty()
{
 "_id" : ObjectId("5ea6f53240e9db6af06a231b"),
 "item" : "notebook2",
 "qty" : 10
}
{
 "_id" : ObjectId("5ea6f53240e9db6af06a231c"),
 "item" : "notebook3",
 "qty" : 13
}
