DALQueryError

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

an exception indicating an error by a working DAL service while processing a query. Generally, this would be an error that the service successfully detected and consequently was able to respond with a legal error response– namely, a VOTable document with an INFO element contains the description of the error. Possible errors will include bad usage by the client, such as query-syntax errors.

Parameters

a message describing the cause of the error. This should be set to the content of the INFO error element.

labelstr

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.

urlstr

the query URL that produced the error
