Ich möchte Juan Carlos Oropeza für die Bereitstellung eines Skripts und von SQLFiddle mit den Testdaten danken. George, das hättest du tun sollen.
Die Abfrage selbst ist ziemlich einfach.
Berechnen Sie zunächst eine einfache Laufsumme (CTE_RunningSum ) und teilen Sie ihn durch 1,000,000 ganze Millionen zu bekommen.
Berechnen Sie dann die laufende Summe erneut mit einer Aufteilung in Millionen.
SQL-Fiddle
Ich habe die Spalten RunningSum eingefügt und Millions im Endergebnis, um zu veranschaulichen, wie die Abfrage funktioniert.
WITH
CTE_RunningSum
AS
(
SELECT
ID
,day_t
,collect
,SUM(collect) OVER(ORDER BY day_t, id) AS RunningSum
,(SUM(collect) OVER(ORDER BY day_t, id)) / 1000000 AS Millions
FROM myTable
)
SELECT
ID
,day_t
,collect
,RunningSum
,Millions
,SUM(collect) OVER(PARTITION BY Millions ORDER BY day_t, id) AS Result
FROM CTE_RunningSum
ORDER BY day_t, id;
Ergebnis
| id | day_t | collect | runningsum | millions | result |
