Question

在Windows 7客户端上使用Oracle 11gR2。我有以下示例表：

我想从中查看将存储所有NUMBER列的总和的视图（即Handled_Package，Expected_Missing_Package，Actual_Missing_Package）每个地点每年的每个月。即输出应如下所示：

我该怎么做？为方便起见，这里是创建和插入脚本：

感谢任何帮助或建议。

Answer 1

看起来像一个简单的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

您的更新会使某些事情变得复杂，这会将非现有区域连接为零行，并使用OVER (PARTITION BY)代替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

后者可能会简化，我必须承认Oracle的分析功能不是我的专长：）
