exception pyvo.dal.DALQueryError(reason=None, label=None, url=None)[source]

an exception indicating an error by a working DAL service while processing a query.

Possible errors will include bad usage by the client, such as query-syntax errors.

the identifying name of the error. This should be the value of the INFO element’s value attribute within the VOTable response that describes the error.
