例子

The following initializes a Bulk() operations builder on the items collection, adds a series of write operations, and calls Bulk.toString() on the bulk builder object.

var bulk = db.items.initializeOrderedBulkOp();
bulk.insert( { item: "abc123", status: "A", defaultQty: 500, points: 5 } );
bulk.insert( { item: "ijk123", status: "A", defaultQty: 100, points: 10 } );
bulk.find( { status: "D" } ).deleteOne();
bulk.toString();
bulk.execute()

The Bulk.toString() returns the following JSON document

{
  acknowledged: true,
  insertedCount: 2,
  insertedIds: [
    { index: 0, _id: ObjectId("627bf4f95e19ff3518448883") },
    { index: 1, _id: ObjectId("627bf4f95e19ff3518448884") }
  ],
  matchedCount: 0,
  modifiedCount: 0,
  deletedCount: 0,
  upsertedCount: 0,
  upsertedIds: []
}
