Hello support,
When I run this query against a 10 billion dataset in an instance of Virtuoso compiled from latest development branch:
select ?d count(?d) {
?s sides:has_for_result ?d.
}
group by ?d
order by asc(?d)
I got this wrong output
d count
LONG VARCHAR LONG VARCHAR
__________________________________

0.2 17323013
0.5 25054759
1 14883927
5 Rows. -- 6823 msec.
because the right output is:
+------+--------------+
| d | count |
+------+--------------+
| 0 | 92070570|
| 0.1 | 380429 |
| 0.2 | 99187593 |

|0.425| 689019 |
| 0.5 |169843469|
| 1 |336567259|
+-----+---------+
For your information, the total number of has_for_result
triples is 698 778 545
Any idea why Virtuoso is counting wrong?
Thanks
