- Bulk.tojson()¶
2.6 新版功能.
Returns a JSON document that contains the number of operations and batches in the Bulk() object.
Example¶
The following initializes a Bulk() operations builder on the items collection, adds a series of write operations, and calls Bulk.tojson() 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" } ).removeOne(); bulk.tojson();
The Bulk.tojson() returns the following JSON document
{ “nInsertOps” : 2, “nUpdateOps” : 0, “nRemoveOps” : 1, “nBatches” : 2 }
