Description: Recursive complex query
Details:
I try to run following query:
with recursive data (cid, rid, fini, ffin) as (
select
po1.cliente_id,
po1.ramo_id,
po1.inicio,
po1.final
from tm_polizas po1
inner join (
select
pol.cliente_id,
pol.ramo_id,
max(pol.final) final
from tm_polizas pol
where pol.final >= (date '2009-01-01')
group by pol.cliente_id,
pol.ramo_id
) x1
on x1.cliente_id = po1.cliente_id
and x1.ramo_id = po1.ramo_id
and x1.final = po1.final
union all
select
po2.cliente_id,
po2.ramo_id,
po2.inicio,
data.ffin final
from tm_polizas po2
inner join data
on po2.cliente_id = data.cid
and po2.ramo_id = data.rid
and po2.final >= (fini - 90)
)
select
cid cliente_id,
rid ramo_id,
min(fini) inicio,
max(ffin) final
from data
group by cid, rid;
and the server report me the error: "ERROR: write failed"
This table contain 5 million rows
Thank
