Wraps exceptions raised by the DB-API underlying the database operation. Driver-specific implementations of the standard DB-API exception types are wrapped by matching sub-types of SQLAlchemy's :class:`DBAPIError` when possible. DB-API's ``Error`` type maps to :class:`DBAPIError` in SQLAlchemy, otherwise the names are identical. Note that there is no guarantee that different DB-API implementations will raise the same exception type for any given error condition. :class:`DBAPIError` features :attr:`~.StatementError.statement` and :attr:`~.StatementError.params` attributes which supply context regarding the specifics of the statement which had an issue, for the typical case when the error was raised within the context of emitting a SQL statement. The wrapped exception object is available in the :attr:`~.StatementError.orig` attribute.
