Hi guys,
Rollup seems to be working correcly to count the number of units, but not the number of trains. Any idea what could be causing that?
The output from the query looks like this. The sum of the Units column in yellow is 53 but the rollup is showing 51. The number of units adds up correctly though...
And here's the oracle SQL query...
select t.year,
t.week,
decode(t.mine_id,NULL,'PF',t.mine_id) as mine_id,
decode(t.product,Null,'LF',t.product) as product,
decode(t.mine_id||'-'||t.product,'-','PF',t.mine_id||'-'||t.product) as code,
count(distinct t.tpps_train_id) as trains,
count(1) as units
from
(
select trn.mine_code as mine_id,
trn.train_tpps_id as tpps_train_id,
round((con.calibrated_weight_total - con.empty_weight_total),2) as tonnes
from widsys.train trn
INNER JOIN widsys.consist con
USING (train_record_id)
where trn.direction = 'N'
and (con.calibrated_weight_total-con.empty_weight_total) > 10
and trn.num_cars > 10
and con.consist_no not like '_L%'
) w,
(
select to_char(td.datetime_act_comp_dump-7/24, 'IYYY') as year,
to_char(td.datetime_act_comp_dump-7/24, 'IW') as week,
td.mine_code as mine_id,
td.train_id as tpps_train_id,
pt.product_type_code as product
from tpps.train_details td
inner join tpps.ore_products op
using (ore_product_key)
inner join tpps.product_types pt
using (product_type_key)
where to_char(td.datetime_act_comp_dump-7/24, 'IYYY') = 2010
and to_char(td.datetime_act_comp_dump-7/24, 'IW') = 12
order by td.datetime_act_comp_dump asc
) t
where w.mine_id = t.mine_id
and w.tpps_train_id = t.tpps_train_id
having t.product is not null or t.mine_id is null
group by
t.year,
t.week,
rollup(
t.mine_id,
t.product)
