MongoDB\Driver\BulkWrite::update — Add an update operation to the bulk
$filter
, array|object $newObj
[, array $updateOptions
] )Adds an update operation to the MongoDB\Driver\BulkWrite.
filter (array|object)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).
newObj (array|object)A document containing either update operators (e.g. $set) or a replacement document (i.e. only field:value expressions).
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.

没有返回值。
