Hi Ivan,
Thanks a lot for your great support and for those fixes. BTW, when do you
plan to announce the official VOS 5.0.4?
Regarding limit 1 offset 2, I am not sure I fully understand what you mean.
For me:
limit 1 => first row
limit 1 offset 0 => first row
limit 1 offset 1 => first row
limit 1 offset 2 => second row
So the following query
> sparql select distinct ?g where {graph ?g {?s ?p ?o}} order by (?g)
> limit 1 offset 2;
should return the second row (if there are at least 2 rows in result set, of
course).
What do you think?
Pierre
