Bulk.getOperations()（mongosh方法）

兼容性

此命令可用于以下环境中托管的部署：

• MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

例子

The following initializes a Bulk() operations builder on the items collection, adds a series of write operations, executes the operations, and then calls getOperations() on the bulk builder object:

var bulk = db.items.initializeUnorderedBulkOp();
for (var i = 1; i <= 1500; i++) {
    bulk.insert( { x: i } );
}
bulk.execute();
bulk.getOperations();

The getOperations() method returns an array with the operations executed. The output shows that MongoDB divided the operations into 2 groups, one with 1000 operations and one with 500. For information on how MongoDB groups the list of bulk write operations, see Bulk.execute() Behavior

虽然该方法会返回返回数组中的所有 1500 个操作，但为了简洁起见，本页省略了一些结果。

      ]
   },

      "originalZeroIndex" : 1000,
      "batchType" : 1,
      "operations" : [
         { "_id" : ObjectId("53a8959f1990ca24d01c654d"), "x" : 1001 },
         ... // Content omitted for brevity
         { "_id" : ObjectId("53a8959f1990ca24d01c6740"), "x" : 1500 }
      ]
   }
]

返回的字段

该数组包含具有以下字段的文档：

originalZeroIndex

Specifies the order in which the operation was added to the bulk operations builder, based on a zero index; e.g. first operation added to the bulk operations builder will have originalZeroIndex value of 0.

batchType

指定写入操作类型。

batchType	操作
1	Insert
2	Update
3	删除

operations

包含操作详细信息的文档数组。
