Как рассчитать отдельные суммы нескольких столбцов в одном запросе

Question

Использование Oracle 11gR2 для клиента Windows 7. У меня есть следующий пример таблицы:

Yr  Mnth  Region City   Handled_Package  Expected_Missing_Package  Actual_Missing_Package 

2012 November Western San Fransisco 200     10       5 
2012 November Western Los Angeles  400     20       15 
2012 November Eastern New York  300     15       20 
2012 November Western Seattle   100     5        7 
2012 November Eastern Philadelphia 200     10       12 
2012 November MidWest Chicago   300     15       15 

2012 December MidWest Detroit   50     3        2 
2012 December Western Los Angeles  300     15       19 
2012 December Eastern New York  400     20       16 
2012 December Eastern Philadelphia 150     8        6 
2012 December MidWest Chicago   200     10       10 

2013 January Eastern New York  200     10       9 
2013 January MidWest Chicago   100     5        7 
2013 January Western San Fransisco 500     25       22 
2013 January Western Los Angeles  200     10       8 
2013 January Europe London   500     25       27 
2013 January Europe Paris   400     20       23 

2013 Februray Europe London   200     10       9 
2013 Februray Eastern Philadelphia 300     15       13 
2013 Februray Eastern NY    400     20       18 
2013 February Western San Fransisco 400     20       12 
2013 Februray Western LA    200     10       8 
2013 Februray MidWest Detroit   300     15       13 

Я хочу, чтобы сделать вид из него, который будет хранить суммы всех столбцов NUMBER (т.е. Handled_Package, Expected_Missing_Package, Actual_Missing_Package) за каждый месяц года для каждого места , То есть вывод должен выглядеть следующим образом:

Yr  Mnth  Region  Handled_Package Expected_Missing_Package Actual_Missing_Package 

2012 November Eastern  500    25      32 
2012 November Europe  0     0       0 
2012 November MidWest  300    15      15 
2012 November Western  700    35      27 

2012 December Eastern  250    13      12 
2012 November Europe  0     0       0 
2012 December MidWest  550    28      22 
2012 December Western  300    15      19 

2013 January  Eastern  200    10      9 
2013 January  Europe  900    45      50 
2013 January  MidWest  100    5       7 
2013 January  Western  700    35      30 

2013 February Eastern  700    35      31 
2013 February Europe  200    10      9 
2013 February MidWest  300    15      13 
2013 February Western  600    30      20 

Как бы я это сделал? Для вашего удобства здесь создаются сценарии создания и вставки:

CREATE TABLE test

    Yr       VARCHAR2(5), 
    Mnth      VARCHAR2(50),

    CITY      VARCHAR2(50),    
    Handled_Package   NUMBER,   
    Expected_Missing_Package NUMBER,  
    Actual_Missing_Package  NUMBER

Получу любую помощь или предложение.

Answer 1

Похоже простой GROUP BY;

SELECT Yr,Mnth,Region, 
    SUM(Handled_Package) Handled_Package, 
    SUM(Expected_Missing_Package) Expected_Missing_Package, 
    SUM(Actual_Missing_Package) Actual_Missing_Package 
FROM TEST 
GROUP BY Yr,Mnth,Region 
ORDER BY Yr,Mnth,Region 

An SQLfiddle to test with.

Ваше обновление немного усложняет ситуацию, оно объединяется в не существующие регионы как нулевые строки и использует OVER (PARTITION BY) вместо GROUP BY;

SELECT DISTINCT r.Yr,r.Mnth,r.Region, 
    COALESCE(SUM(t.Handled_Package) 
    OVER (PARTITION BY r.Yr,r.Mnth,r.Region), 0) Handled_Package, 
    COALESCE(SUM(t.Expected_Missing_Package) 
    OVER (PARTITION BY r.Yr,r.Mnth,r.Region), 0) Expected_Missing_Package, 
    COALESCE(SUM(t.Actual_Missing_Package) 
    OVER (PARTITION BY r.Yr,r.Mnth,r.Region), 0) Actual_Missing_Package 
FROM TEST t 
RIGHT JOIN (
    SELECT DISTINCT t1.Region,t2.Yr,t2.Mnth FROM TEST t1 CROSS JOIN TEST t2 
) r 
ON t.Yr = r.Yr AND t.Mnth=r.Mnth AND t.Region=r.Region 
ORDER BY r.Yr,r.Mnth,r.Region

Последнее, вероятно, может быть упрощена, я должен признать, аналитические функции Oracle, не моя специальность :)
