Try this:
select ?g { graph ?g {} }
or even this:
select (count(?g) as ?count) { graph ?g {} }

Hi all,
I am trying to make some basic statistics using SPARQL queries on my endpoint
backed by MarkLogic.
Today, I just wanted to retrieve the number of named graphs with the following
query:
select distinct ?g where {
graph ?g {
?s ?p ?o
}
}
I realize that the operation works fine when I limit to 2 (why?) and then for
the rest, I have a time exceed limit.
Did someone also experience this issue before?
Thanks in advance.
Best,
Ghislain
