Alla case kan enkelt göras med UNION
uttalande (se sqlFiddle
för resultat):
(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
Men prestandan kanske inte är riktigt bra med den typen av frågor, så jag säger inte att det är den bästa möjliga lösningen - men det fungerar.
