options
| Option | Type | Description |
|---|---|---|
| session | MongoDB\Driver\Session |
A session to associate with the operation. |
| writeConcern | MongoDB\Driver\WriteConcern |
A write concern to apply to the operation. |
If you are using a "session" which has a transaction in progress, you cannot specify a "readConcern" or "writeConcern" option. This will result in an MongoDB\Driver\Exception\InvalidArgumentException being thrown. Instead, you should set these two options when you create the transaction with MongoDB\Driver\Session::startTransaction().
Returns MongoDB\Driver\Cursor on success.
| 版本 | 说明 |
|---|---|
| 1.4.4 | MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the "session" option is used in combination with an unacknowledged write concern. |
