Можете да използвате SUM/CASE
или (SUM/DECODE
ако предпочитате)
Select
COUNT(*) TOTAL_RECORDS ,
SUM(case when status = 'PENDING' then 1 else 0 END) TOTAL_PENDING,
SUM(case when status = 'NOT_REQUIRED' then 1 else 0 END) TOTAL_NOT_REQUIRED,
SUM(case when status = 'ERROR' then 1 else 0 END) TOTAL_ERROR
FROM temp25
Можете също да използвате pivot, но получаването на count(*) е малко грозно
WITH
COUNTS AS(
select *
from (
select status
from TEMP25 t
)
pivot
(
count(status)
for status in ('PENDING' AS TOTAL_PENDING,
'NOT_REQUIRED' AS TOTAL_NOT_REQUIRED,
'ERROR' AS TOTAL_ERROR)
))
SELECT COUNT(*) total_records,
total_pending,
total_not_required,
total_error
FROM temp25,
counts
GROUP BY total_pending,
total_not_required,
total_error
