Hello,
I wonder whether Virtuoso has different processing mechanisms on the
following queries:
TYPE1:
------------------------------------------------------
SELECT * WHERE {
?var1 :p1 ?var2.
FILTER (?var1 IN ( :rsc1, :rsc2, :rsc3)).
?var3 :p2 ?var1.
}
-------------------------------------------------------
TYPE2:
-------------------------------------------------------
SELECT * WHERE {
?var1 :p1 ?var2.
?var3 :p2 ?var1.
FILTER (?var1 IN ( :rsc1, :rsc2, :rsc3 )).
}
First query type has filter block in the position just after triple which
includes variable to be filtered. Second query type has filter block at the
end of the all triples.
Best Regards,
Burak Yönyül
