Builds a find operation for an update/updateOne/delete/deleteOne/replaceOne. Returns a builder object used to complete the definition of the operation.

参数

selector

Document

返回

FindOperators

示例

const bulkOp = collection.initializeOrderedBulkOp()

// Add an updateOne to the bulkOp
bulkOp.find({ a: 1 }).updateOne({ $set: { b: 2 } })

// Add an updateMany to the bulkOp
bulkOp.find({ c: 3 }).update({ $set: { d: 4 } })

// Add an upsert
bulkOp.find({ e: 5 }).upsert().updateOne({ $set: { f: 6 } })

// Add a deletion
bulkOp.find({ g: 7 }).deleteOne()

// Add a multi deletion
bulkOp.find({ h: 8 }).delete()

// Add a replaceOne
bulkOp.find({ i: 9 }).replaceOne({ writeConcern: { j: 10 } })

// Update using a pipeline (requires Mongodb 4.2 or higher)
bulk.find({ k: 11, y: { $exists: true }, z: { $exists: true } }).updateOne([
  { $set: { total: { $sum: ['$y', '$z'] } } }
