MongoDB\Driver\BulkWrite::updateAdd an update operation to the bulk

说明

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

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

参数

filter (array|object)

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

newObj (array|object)

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

updateOptions

updateOptions
Option Type Description Default
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 bool Update only the first matching document (multi=false), or all matching documents (multi=true). FALSE
upsert bool 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

返回值

版本 说明
