Hi,
I believe I've found a bug with DELETE EDGE in OrientDB, and consequently
in Oriento. It seems OrientDB is ignoring the class provided in queries
with format:
DELETE EDGE *class* FROM rid TO rid
And thus it may delete more edges than intended.
I've ran the below code in both studio and console and the results were the
same:
CREATE CLASS likes extends E
CREATE CLASS favourite extends E
CREATE CLASS person extends V
create vertex Person set name = 'Luca'
create vertex Person set name = 'Bill'
CREATE EDGE likes from #15:1 to #15:0
CREATE EDGE favourite from #15:1 to #15:0
select expand(outE()) from #15:1
# 2 results
DELETE EDGE favourite from #15:1 to #15:0
# expecting 1 but result was 2
select expand(outE()) from #15:1
# 0 results
If I use 'where' it only deletes 1 edge as expected:
DELETE EDGE from #15:1 to #15:0 where @class='favourite'
Thanks
