Verwenden Sie die Funktion jsonb_array_elements()
in einem lateralen Join in der from-Klausel:
select cname, sum(coalesce(value, '0')::int) as value
from (
select
p06->>'cname' as cname,
value->>'progress' as value
from ryzom_characters
cross join jsonb_array_elements(p06->'rpjobs')
where cid = 675010
) s
group by cname
order by value desc
limit 50;
Sie können Left Join anstelle von Cross Join verwenden, um die Abfrage vor inkonsistenten Daten zu schützen:
left join jsonb_array_elements(p06->'rpjobs')
on jsonb_typeof(p06->'rpjobs') = 'array'
where p06->'rpjobs' <> 'null'
