@nagaraja sosale ramaswamy, I'm trying to understand how this query works.
Specifically, I can't see how "in" and "out" are defined. I built a quick
sample database using this script, but when I run the query (either yours
or Andrey's), I get a syntax error saying "invalid script". I'm using the
BROWSE tab of OrientDB Studio, version 2.2.8. Has something changed in the
language since this was posted, or am I missing something? I found the
link to this topic in the OrientDB 2.2.x documentation
<http://orientdb.com/docs/2.2.x/Query-Examples.html>.
Initial setup:
insert into V (name) values ('V1'),('V2')
create edge E from (select from V where name = 'V1') to (select from V where
name = 'V2') set count = 17
create edge E from (select from V where name = 'V2') to (select from V where
name = 'V1') set count = 3
Test query (you will have to substitute "#17:0" for the actual key in your
DB):
select v.name, sum(count) as cnt from (select if(eval("in=#17:0"),out,in) as
v,count from E where (in=#17:0 or out=#17:0)) order by cnt desc group by v
