Hello.
I am running VOS 6.01.3127 and have strange problem.
I have a graph <graph> with triple <s> <p> <o>.
When I'm executing the query
MODIFY <graph> DELETE {<s> <p> <o>} INSERT {<s> <p> <o>} (both, followed and
not with "WHERE {<s> <p> <o>}" ),
which as I expect should leave my triple without any changes, but Virtuoso says
"Modify <graph>, delete 1 and insert 0 triples -- done" and actually delete
this triple.
I create some workaround to avoid such queries in my application.
But is it right behaviour or bug of Virtuoso SPARQL Endpoint?
Best regards, Alexander A. Zaripov
