[Virtuoso-users] Help with delete query

[Sebastian Trueg]

Is it possible to delete a set of graphs in one query?
Basically I would like to do something like (I know that the syntax
below does not work):

clear graph ?g where {
    ?g nie:indexGraphFor ?r .
    ?r nie:isPartOf <something> . }

Currently I do this on the client side which is way slower of course.

Any hints appreciated. If possible I would like to avoid SQL queries.

Cheers,
Sebastian
