MongoDB\Driver\Server::executeReadWriteCommand — Execute a database command that reads and writes on this server
$db
, MongoDB\Driver\Command $command
, array $options
= array()): MongoDB\Driver\CursorExecutes the command on this server.
This method will apply logic that is specific to commands that read and write
(e.g.
» aggregate)
and take the MongoDB server version into account. The
"readConcern"
and "writeConcern"
options will default to the corresponding values from the
MongoDB Connection
URI.
db
(string)コマンドを実行するデータベースの名前。
command
(MongoDB\Driver\Command)実行するコマンド。
options
Option | Type | Description |
---|---|---|
readConcern | MongoDB\Driver\ReadConcern |
A read concern to apply to the operation. This option is available in MongoDB 3.2+ and will result in an exception at execution time if specified for an older server version. |
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().
成功した場合に MongoDB\Driver\Cursor を返します。
"session"
option is used with an associated transaction in combination with a "readConcern"
or "writeConcern"
option."session"
option is used in combination with an unacknowledged write concern.
バージョン | 説明 |
---|---|
PECL mongodb 1.4.4 |
MongoDB\Driver\Exception\InvalidArgumentException
will be thrown if the "session" option is used in
combination with an unacknowledged write concern.
|
注意: It is the caller's responsibility to ensure that the server is capable of executing the write operation. For example, executing a write operation on a secondary (excluding its "local" database) will fail.
