MongoDB\Driver\Manager::executeReadWriteCommand — Execute a database command that reads and writes
说明
$db, MongoDB\Driver\Command $command, ?array $options = null): MongoDB\Driver\CursorExecutes the command on the primary server.
This method will apply logic that is specific to commands that read and write
(e.g. » aggregate).
Default values for the "readConcern" and
"writeConcern" options will be inferred from an active
transaction (indicated by the "session" option), followed
by the 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.
options-
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.
警告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().
返回值
Returns MongoDB\Driver\Cursor on success.
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).
