oracle query with pivot and row totals - oracle

Question

Here is my entire requirement along with create and insert commands.
create table sample
( schedule_id varchar2(256),
schedule_details varchar2(256),
pod_name varchar2(256),
milestone varchar2(256),
metric_column varchar2(256),
metric_value varchar2(4000));
insert into sample values ('23456','details','ABCD','M1','status','DONE');
insert into sample values ('123456','details','ABCD','M1','progress','GREEN');
insert into sample values ('123456','details','ABCD','M1','last_reported','2016-03-18 04:18:56');
insert into sample values ('123456','det','ABCD','M2','status','DONE');
insert into sample values ('123456','det','ABCD','M2','progress','RED');
insert into sample values ('123456','det','ABCD','M2','last_reported','2016-03-19 04:18:56');
insert into sample values ('123456','det','ABCD','M3','status','SKIP');
insert into sample values ('123456','det','ABCD','M3','progress','YELLOW');
insert into sample values ('123456','det','ABCD','M3','last_reported','2016-03-20 04:18:56');
insert into sample values ('123456','det''EFGH','M1','status','DONE');
insert into sample values ('123456','det','EFGH','M1','progress','GREEN');
insert into sample values ('123456','det','EFGH','M1','last_reported','2016-03-10 04:18:56');
insert into sample values ('123456','det','EFGH','M2','status','DONE');
insert into sample values ('123456','det','EFGH','M2','progress','RED');
insert into sample values ('123456','det','EFGH','M2','last_reported','2016-03-12 04:18:56');
insert into sample values ('123456','det','EFGH','M3','status','SKIP');
insert into sample values ('123456','det','EFGH','M3','progress','YELLOW');
insert into sample values ('123456','det','EFGH','M3','last_reported','2016-03-11 04:18:56');
insert into sample values ('7890','det','ABCD','M1','status','DONE');
insert into sample values ('7890','det','ABCD','M1','progress','GREEN');
insert into sample values ('7890','det','ABCD','M1','last_reported','2016-04-18 04:18:56');
insert into sample values ('7890','det','ABCD','M2','status','DONE');
insert into sample values ('7890','det','ABCD','M2','progress','RED');
insert into sample values ('7890','det','ABCD','M2','last_reported','2016-04-19 04:18:56');
insert into sample values ('7890','det','ABCD','M3','status','FAILED');
insert into sample values ('7890','det','ABCD','M3','progress','GREEN');
insert into sample values ('7890','det','ABCD','M3','last_reported','2016-04-20 04:18:56');
insert into sample values ('7890','det','PQRS','M1','status','DONE');
insert into sample values ('7890','det','PQRS','M1','progress','GREEN');
insert into sample values ('7890','det','PQRS','M1','last_reported','2016-04-10 04:18:56');
insert into sample values ('7890','det','PQRS','M2','status','DONE');
insert into sample values ('7890','det','PQRS','M2','progress','RED');
insert into sample values ('7890','det','PQRS','M2','last_reported','2016-04-11 04:18:56');
insert into sample values ('7890','det','PQRS','M3','status','SKIP');
insert into sample values ('7890','det','PQRS','M3','progress','GREEN');
insert into sample values ('7890','det','PQRS','M3','last_reported','2016-04-12 04:18:56');
my output is
SCHEDULE_ID | STATUS_DONE | STATUS_SKIP | STATUS_FAILED | STATUS_TOTAL | PROGRESS_RED | PROGRESS_GREEN | PROGRESS_YELLOW | PROGRESS_TOTAL
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
123456 | 1 | 1 | 0 | 2 | 1 | 0 | 1 | 2
7890 | 0 | 2 | 0 | 2 | 0 | 1 | 1 | 2
The query needs to fetch the distinct number of pod_name for each schedule_id. For each pod it needs to take the metric_column->status and metric_column->progress of the milestone which has latest metric_column->last_reported. So the value of STATUS_DONE,is the number of POD_NAME that have the latest milestone (based on last_reported) as status DONE.
For eg for schedule id 123456, the pod ABCD, the status and progress of milestone M3 needs to be taken as M3 has the latest last_reported compared to M1 and M2.
I have the query with distinct pod name without taking into consideration the latest milestone.
select *
from (SELECT SCHEDULE_ID,SCHEDULE_DETAILS,POD_NAME,
CASE WHEN GROUPING(value) = 0
THEN value
ELSE CASE WHEN METRIC_COLUMN='status'
THEN 'STATUS_TOTAL'
ELSE 'PROGRESS_TOTAL'
END
END value
FROM sample
WHERE metric_column IN ('status','progress' )
GROUP BY SCHEDULE_ID,SCHEDULE_DETAILS,POD_NAME, METRIC_COLUMN, ROLLUP(value))
PIVOT (COUNT( DISTINCT POD_NAME) FOR VALUE in ('DONE' AS "DONE",'SKIP' AS "SKIP",'FAILED' AS "FAILED",'STATUS_TOTAL' AS "STATUS_TOTAL",'GREEN' AS GREEN,'RED' AS "RED",'YELLOW' AS "YELLOW", 'PROGRESS_TOTAL' AS "PROGRESS_TOTAL"));
