MongoDB\Driver\Manager::executeReadWriteCommand — Execute a database command that reads and writes
说明
final public MongoDB\Driver\Manager::executeReadWriteCommand
( string $db
, MongoDB\Driver\Command $command
[, array $options = array()
] ) : MongoDB\Driver\Cursor
Executes the command on the primary 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.
参数
db(string)The name of the database on which to execute the command.
command(MongoDB\Driver\Command)The command to execute.

| 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.

Warning
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().
错误／异常
- Throws MongoDB\Driver\Exception\InvalidArgumentException if the
"session"option is used with an associated transaction in combination with a"readConcern"or"writeConcern"option. - Throws MongoDB\Driver\Exception\InvalidArgumentException if the
"session"option is used in combination with an unacknowledged write concern. - Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
- Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
- Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
- Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid command).
