MongoDB\Driver\Manager::executeWriteCommand — Execute a database command that 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 write (e.g.
» drop).
The default value for the "writeConcern" option will be
inferred from an active transaction (indicated by the
"session" option), followed by the
connection URI.
注意: This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Manager::executeBulkWrite() for those operations.
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 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).
