RussianFrage
Ich habe eine Abfrage geschrieben, einige Daten zu sammeln, in einem Auto-Update-Box & Whisker Diagramm in Excel angezeigt werden soll. Ich mag Rollup verwenden, um Zusammenfassungszeilen für jede Art von train_line (PF und MJ) enthalten in dem Excel-Diagramm zu erstellen.
Kann ich das mit Rollup?
Ich habe versucht, meinen Kopf um Rollup zu bekommen, aber ich bin nicht weit zu bekommen. Ich habe gerade versucht es um zufällige Dinge in meiner Gruppe-durch Umwickeln, aber es hat nicht getan, was ich haben wollte.
Hier ist, was die ersten paar Spalten der Ergebnisse aussehen.
DUMP_YEAR DUMP_WEEK LINE MINE PRODUCT CODE
2009 30 MJ MJ C MJ-C
2009 30 PF BR F BR-F
2009 30 PF BR L BR-L
2009 30 PF HD F HD-F
2009 30 PF HD L HD-L
2009 30 PF MA F MA-F
2009 30 PF MA L MA-L
2009 30 PF NM F NM-F
2009 30 PF NM L NM-L
2009 30 PF PA F PA-F
2009 30 PF PA L PA-L
2009 30 PF TP F TP-F
2009 30 PF TP L TP-L
2009 30 PF WA F WA-F
2009 30 PF WA L WA-L
2009 30 PF YA F YA-F
Und hier ist meine SQL-Abfrage.

Lösung
Sie würden verwenden ROLLUP- hierarchische Teilergebnisse für Ihre Anfrage zu erzeugen, das heißt:
SQL> WITH DATA AS (
2 SELECT 'i' || MOD(ROWNUM, 1) dim1,
3 'j' || MOD(ROWNUM, 2) dim2,
4 'k' || MOD(ROWNUM, 3) dim3,
5 ROWNUM qty
6 FROM dual
7 CONNECT BY LEVEL <= 100
8 )
9 SELECT dim1, dim2, dim3, SUM(qty) tot
10 FROM DATA
11 GROUP BY dim1, rollup(dim2,dim3)
12 ORDER BY 1, 2, 3;
DIM1 DIM2 DIM3 TOT
----- ----- ----- ----------
i0 j0 k0 816
i0 j0 k1 884
i0 j0 k2 850
i0 j0 2550 (*)
i0 j1 k0 867
i0 j1 k1 833
i0 j1 k2 800
i0 j1 2500 (*)
i0 5050 (*)
Die ROLLUP-Klausel erzeugt, um die Linien markiert (*)
Wenn Sie nur einen Satz von Zwischensummen erhalten möchten und nicht alle Hierarchieebenen, können Sie die GROUPING SETS Klausel, dh:
SQL> WITH DATA AS (
2 SELECT 'i' || MOD(ROWNUM, 1) dim1,
3 'j' || MOD(ROWNUM, 2) dim2,
4 'k' || MOD(ROWNUM, 3) dim3,
5 ROWNUM qty
6 FROM dual
7 CONNECT BY LEVEL <= 100
8 )
9 SELECT dim1, dim2, dim3, SUM(qty) tot
10 FROM DATA
11 GROUP BY GROUPING SETS (
12 (dim1, dim2, dim3), -- detail
13 (dim1) -- total
14 )
15 ORDER BY 1, 2, 3;
DIM1 DIM2 DIM3 TOT
----- ----- ----- ----------
i0 j0 k0 816
i0 j0 k1 884
i0 j0 k2 850
i0 j1 k0 867
i0 j1 k1 833
i0 j1 k2 800
i0 5050
