I would use "DELETE WHERE { ... }" -- see

Hi Maxence,
Hello,
Blank nodes are anonymous -- the nodes without labels in a visual graph
of your model.
In an RDF store these nodes are given identifiers in order to include
the nodes in statements. The actual value of a blank node's identifier
though is local to the graph it is part of. Generating another graph via
a query is very likely to assign different values, and even two
identical queries against the same graph are likely to return different
blank node identifiers.
Thanks for your answer. So that's a feature.
The reason why I encountered this problem is that I wanted to remove a part
of my model. So this query was supposed to return the statements to remove
from my model.
I have to do it another way. For information, since I have no experience
yet of performing such an operation, what is your favorite way of removing
part of your model when it contains blank nodes ? I mean, the less painful
one, of cource :-)
Regards,
Maxence
