Bulk.find.removeOne()
On this page
Tip
Starting in version 3.2, MongoDB also provides the
db.collection.bulkWrite()
method for performing bulk
write operations.
Description
Bulk.find.removeOne()
Adds a single document remove operation to a bulk operations list. Use the
Bulk.find()
method to specify the condition that determines which document to remove. TheBulk.find.removeOne()
limits the removal to one document. To remove multiple documents, seeBulk.find.remove()
.
Example
The following example initializes a Bulk()
operations builder
for the items
collection and adds two
Bulk.find.removeOne()
operations to the list of operations.
Each remove operation removes just one document: one document with the
status
equal to "D"
and another document with the status
equal to "P"
.
var bulk = db.items.initializeUnorderedBulkOp(); bulk.find( { status: "D" } ).removeOne(); bulk.find( { status: "P" } ).removeOne(); bulk.execute();
