आप एक पुनरावर्ती सीटीई का उपयोग कर सकते हैं:
with recursive t(account_id, device_id) as (
select 1, 10 union all
select 1, 11 union all
select 1, 12 union all
select 2, 10 union all
select 3, 11 union all
select 3, 13 union all
select 3, 14 union all
select 4, 15 union all
select 5, 15 union all
select 6, 16
),
a as (
select distinct t.account_id as a, t2.account_id as a2
from t join
t t2
on t2.device_id = t.device_id and t.account_id >= t2.account_id
),
cte as (
select a.a, a.a2 as mina
from a
union all
select a.a, cte.a
from cte join
a
on a.a2 = cte.a and a.a > cte.a
)
select grp, array_agg(a)
from (select a, min(mina) as grp
from cte
group by a
) a
group by grp;
यहां एक SQL Fiddle है।
