MongoDB\Driver\BulkWriteCommand::deleteOne

Add a deleteOne operation

Description

public void MongoDB\Driver\BulkWriteCommand::deleteOne(string $namespace, arrayobject $filter, arraynull $options = null)

Add a deleteOne operation to the MongoDB\Driver\BulkWriteCommand. The first document matching filter in the collection identified by namespace will be deleted.

Parameters

namespace (string)

A fully qualified namespace (e.g. "databaseName.collectionName").

filter (arrayobject)

The » query predicate. An empty predicate will match all documents in the collection.

Note: When evaluating query criteria, MongoDB compares types and values according to its own » comparison rules for BSON types, which differs from PHP's comparison and type juggling rules. When matching a special BSON type the query criteria should use the respective BSON class (e.g. use MongoDB\BSON\ObjectId to match an » ObjectId).

options

options
Option Type Description Default
collation arrayobject

» Collation allows users to specify language-specific rules for string comparison, such as rules for lettercase and accent marks. When specifying collation, the "locale" field is mandatory; all other collation fields are optional. For descriptions of the fields, see » Collation Document.

If the collation is unspecified but the collection has a default collation, the operation uses the collation specified for the collection. If no collation is specified for the collection or for the operation, MongoDB uses the simple binary comparison used in prior versions for string comparisons.

This option is available in MongoDB 3.4+ and will result in an exception at execution time if specified for an older server version.

hint stringarrayobject

Index specification. Specify either the index name as a string or the index key pattern. If specified, then the query system will only consider plans using the hinted index.

Return Values

No value is returned.

Errors/Exceptions

  • Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
