MongoDB\Driver\BulkWrite::update — Add an update operation to the bulk
$filter, array|object $newObj, ?array $updateOptions = null): voidAdds an update operation to the MongoDB\Driver\BulkWrite.
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
| 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 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.

| バージョン | 説明 |
|---|---|
| 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.
