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

说明

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

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.

注意: 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), a replacement document (i.e. only field:value expressions), or an » aggregation pipeline.

updateOptions

**updateOptions**
Option	Type	Description	Default
arrayFilters	array	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.
hint	string\|array\|object	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. This option is available in MongoDB 4.2+ and will result in an exception at execution time if specified for an older server version.
multi	bool	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	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

没有返回值。

错误／异常

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

更新日志

版本	说明
PECL mongodb 1.7.0	Added the `"hint"` option.
PECL mongodb 1.6.0	The `newObj` parameter now accepts an aggregation pipeline. This feature requires MongoDB 4.2+ and will result in an exception at execution time if specified for an older server version.
PECL mongodb 1.5.0	Using the `"arrayFilters"` option will result in an exception at execution time if unsupported by the server. Previously, no exception would be thrown and the option may have been ignored.
PECL mongodb 1.4.0	Added the `"arrayFilters"` option.
PECL mongodb 1.2.0	Added the `"collation"` option.
