MongoDB\Driver\BulkWrite::update — Add an update operation to the bulk

Beschreibung

public MongoDB\Driver\BulkWrite::update ( array|object $filter , array|object $newObj [, array $updateOptions ] ) : void

Adds an update operation to the MongoDB\Driver\BulkWrite.

Parameter-Liste

filter

The search filter.

newObj (array|object)

A document containing either update operators (e.g. $set), a replacement document (i.e. only field:value expressions), or an » aggregation pipeline.

updateOptions

updateOptions
Option Type Description Default
arrayFilters array|object

An array of filter documents that determines which array elements to modify for an update operation on an array field. See » Specify arrayFilters for Array Update Operations in the MongoDB manual for more information.

This option is available in MongoDB 3.6+ and will result in an exception at execution time if specified for an older server version.

collation array|object

» 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.

multi boolean Update only the first matching document if FALSE, or all matching documents TRUE. This option cannot be TRUE if newObj is a replacement document. FALSE
upsert boolean If filter does not match an existing document, insert a single document. The document will be created from newObj if it is a replacement document (i.e. no update operators); otherwise, the operators in newObj will be applied to filter to create the new document. FALSE
