Sql 以一个领域为中心？

我使用IBMDB2SQL

以下是我当前的查询：

select 
EXSHPE as "Shape",
EXDLVY as "Delivery",

  Sum(Case When EXSURF = 'Print' Then EXRLTO Else 0 End) As Retail_Print,
  Sum(Case When EXSURF = 'Pattern' Then EXRLTO Else 0 End) as Retail_Pattern,
  Sum(Case When EXSURF = 'Solid' Then EXRLTO Else 0 End) As Retail_Solid,
  Sum(Case When EXSURF = 'UnknownA' Then EXRLTO Else 0 End) as Retail_UnknownA,
  Sum(Case When EXSURF = 'UnknownB' Then EXRLTO Else 0 End) As Retail_UnknownB,
  Sum(Case When EXSURF = 'UnknownC' Then EXRLTO Else 0 End) as Retail_UnknownC,

  Sum(Case When EXSURF = 'Print' Then EXWHLO Else 0 End) As Wholesale_Print,
  Sum(Case When EXSURF = 'Pattern' Then EXWHLO Else 0 End) as Wholesale_Pattern,
  Sum(Case When EXSURF = 'Solid' Then EXWHLO Else 0 End) As Wholesale_Solid,
  Sum(Case When EXSURF = 'UnknownA' Then EXWHLO Else 0 End) as Wholesale_UnknownA,
  Sum(Case When EXSURF = 'UnknownB' Then EXWHLO Else 0 End) As Wholesale_UnknownB,
  Sum(Case When EXSURF = 'UnknownC' Then EXWHLO Else 0 End) as Wholesale_UnknownC,

  Sum(Case When EXSURF = 'Print' Then EXUNTO Else 0 End) As Units_Print,
  Sum(Case When EXSURF = 'Pattern' Then EXUNTO Else 0 End) as Units_Pattern,
  Sum(Case When EXSURF = 'Solid' Then EXUNTO Else 0 End) As Units_Solid,
  Sum(Case When EXSURF = 'UnknownA' Then EXUNTO Else 0 End) as Units_UnknownA,
  Sum(Case When EXSURF = 'UnknownB' Then EXUNTO Else 0 End) As Units_UnknownB,
  Sum(Case When EXSURF = 'UnknownC' Then EXUNTO Else 0 End) as Units_UnknownC,

  Sum(Case When EXSURF = 'Print' Then EXAURA Else 0 End) As Actual_AUR_Print,
  Sum(Case When EXSURF = 'Pattern' Then EXAURA Else 0 End) as Actual_AUR_Pattern,
  Sum(Case When EXSURF = 'Solid' Then EXAURA Else 0 End) As Actual_AUR_Solid,
  Sum(Case When EXSURF = 'UnknownA' Then EXAURA Else 0 End) as Actual_AUR_UnknownA,
  Sum(Case When EXSURF = 'UnknownB' Then EXAURA Else 0 End) As Actual_AUR_UnknownB,
  Sum(Case When EXSURF = 'UnknownC' Then EXAURA Else 0 End) as Actual_AUR_UnknownC,

  Sum(Case When EXSURF = 'Print' Then EXMERA Else 0 End) As Merch_AUR_Print,
  Sum(Case When EXSURF = 'Pattern' Then EXMERA Else 0 End) as Merch_AUR_Pattern,
  Sum(Case When EXSURF = 'Solid' Then EXMERA Else 0 End) As Merch_AUR_Solid,
  Sum(Case When EXSURF = 'UnknownA' Then EXMERA Else 0 End) as Merch_AUR_UnknownA,
  Sum(Case When EXSURF = 'UnknownB' Then EXMERA Else 0 End) As Merch_AUR_UnknownB,
  Sum(Case When EXSURF = 'UnknownC' Then EXMERA Else 0 End) as Merch_AUR_UnknownC

from EXOWMSPD
Where (EXCO || '/' || EXDIV)  = ?
Group By
  EXSHPE,
  EXDLVY
Order By
  EXSHPE DESC,
  EXDLVY DESC

数据库如下所示：

我需要旋转曲面，但要动态。 问题是，我只知道前3个曲面描述。但我需要准备最多6分钟

有没有一种方法可以动态地旋转它来抓取前6个曲面

例如

RETAIL_DOLLARS_1   10.00
RETAIL_DOLLARS_2   20.00
RETAIL_DOLLARS_3   50.00
RETAIL_DOLLARS_4   0.00
RETAIL_DOLLARS_5   0.00
RETAIL_DOLLARS_6   0.00

在本例中，找到了3个曲面的数据，我希望用0填充其他3个曲面

我用它来制作一个报告，我将隐藏那些表面描述等于“”的列

有办法做到这一点吗

谢谢

如果您想在各个维度上对数据进行多维数据集，请尝试

 GROUP BY CUBE

子句

DB2的哪个版本？我知道iSeries没有

PIVOT（）

-类型的函数-您必须手动对其进行透视。但是，您当前的

WHERE

子句将执行得非常糟糕（因为您不能在

EXCO

/

EXDIV

上使用任何索引）-最好在程序代码中拆分主机变量，并分别比较字段。
