Semua kasus dapat dengan mudah dilakukan menggunakan UNION
pernyataan (lihat sqlFiddle
untuk hasil):
(SELECT v.country,
v.site,
SUM(CASE WHEN v.status_id = 1 THEN 1 ELSE 0 END) Total_SuspectedViolations,
SUM(CASE WHEN v.status_id = 2 THEN 1 ELSE 0 END) Total_ConfirmedViolations,
SUM(CASE WHEN v.status_id = 3 THEN 1 ELSE 0 END) Total_ConfirmedNoViolations,
SUM(CASE WHEN v.status_id = 4 THEN 1 ELSE 0 END) Total_NotDetermined,
COUNT(*) Total,
0 'isAll'
FROM violations v
GROUP BY v.country, v.site)
union(
SELECT v.country,
'- All -',
SUM(CASE WHEN v.status_id = 1 THEN 1 ELSE 0 END) Total_SuspectedViolations,
SUM(CASE WHEN v.status_id = 2 THEN 1 ELSE 0 END) Total_ConfirmedViolations,
SUM(CASE WHEN v.status_id = 3 THEN 1 ELSE 0 END) Total_ConfirmedNoViolations,
SUM(CASE WHEN v.status_id = 4 THEN 1 ELSE 0 END) Total_NotDetermined,
COUNT(*) Total,
1 'isAll'
FROM violations v
GROUP BY v.country)
UNION (
SELECT '- All -',
'- All -',
SUM(CASE WHEN v.status_id = 1 THEN 1 ELSE 0 END) Total_SuspectedViolations,
SUM(CASE WHEN v.status_id = 2 THEN 1 ELSE 0 END) Total_ConfirmedViolations,
SUM(CASE WHEN v.status_id = 3 THEN 1 ELSE 0 END) Total_ConfirmedNoViolations,
SUM(CASE WHEN v.status_id = 4 THEN 1 ELSE 0 END) Total_NotDetermined,
COUNT(*) Total,
1 'isAll'
FROM violations v)
ORDER BY country, isAll DESC, site
Namun, kinerjanya mungkin tidak terlalu bagus dengan kueri semacam itu, jadi saya tidak mengatakan itu solusi terbaik - tetapi berhasil.
