Sql server 如何从多个列（在sql中）创建交叉选项卡（在crystal中）

我在SQL中有5列，需要在Crystal中转换为交叉表

这就是我所拥有的：

 Key  | RELATIONSHIP    | DISABLED | LIMITED | RURAL | IMMIGRANT
-----------------------------------------------------------------
  1   | Other Dependent |   Yes    |   No    |  No   |   No
  2   | Victim/Survivor |   No     |   No    |  No   |   No
  3   | Victim/Survivor |   Yes    |   No    |  No   |   No
  4   | Child           |   No     |   No    |  No   |   No
  5   | Victim/Survivor |   No     |   No    |  No   |   No
  6   | Victim/Survivor |   No     |   No    |  No   |   No
  7   | Child           |   No     |   No    |  No   |   No
  8   | Victim/Survivor |   No     |   Yes   |  Yes  |   Yes
  9   | Child           |   No     |   Yes   |  Yes  |   Yes
  10  | Child           |   No     |   Yes   |  Yes  |   Yes

这就是我希望交叉表的外观（键上的不同计数）：

我在Crystal中使用了这个公式来组合4列（字段名={@OTHERDEMO}）

…然后以@OTHERDEMO作为行，以RELATIONSHIP作为列，在键上使用不同的计数进行交叉制表：

问题是，一旦crystal点击第一个“是”，它就会停止计数，从而无法在交叉表中正确分类。所以我得到了一个表，它首先计算残疾并给出正确的显示，然后计算有限的残疾并给出一些信息，然后转储所有其他信息

在过去，我做过多个条件公式

IF {TABLE.DISABLED} = "YES" AND {TABLE.RELATIONSHIP} = "Victim/Survivor" THEN {TABLE.KEY} ELSE {@NULL} 
(the @null formula is because Crystal, notoriously, gets confused with nulls.)

…然后对键进行不同的计数，最后在页脚处求和

我相信还有另一种方法可以做到这一点。任何帮助/想法都将不胜感激。

如果您将这些“演示”列解压成行，将使交叉表变得非常简单

select 
  u.[Key], 
  u.[RELATIONSHIP], 
  u.[DEMO]
from 
  Table1
  unpivot (
    [b] for [DEMO] in ([DISABLED], [LIMITED], [RURAL], [IMMIGRANT])
  ) u
where
    u.[b] = 'Yes'

或者，如果您停留在SQL2000兼容级别上，您可以手动取消选择“是”值

select [Key], [REALTIONSHIP], [DEMO] = cast('DISABLED' as varchar(20)) 
from Table1 
where [DISABLED] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('LIMITED' as varchar(20)) 
from Table1 
where [LIMITED] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('RURAL' as varchar(20)) 
from Table1 
where [RURAL] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('IMMIGRANT' as varchar(20)) 
from Table1 
where [IMMIGRANT] = 'Yes'

---

对于交叉表，在键列上使用计数（也称为行计数），[DEMO]在行上使用计数，而[RELATIONSHIP]在列上使用计数。

允许您更改查询/数据源吗？哦！美好的这太完美了。我以前从未遇到过“unpivot”。感谢更新Welp，进入那里，发现由于我们的一些系统需求，兼容性模式被设置为SQL2000。苏呜。。。。看来我得走很长的路/叹息

select 
  u.[Key], 
  u.[RELATIONSHIP], 
  u.[DEMO]
from 
  Table1
  unpivot (
    [b] for [DEMO] in ([DISABLED], [LIMITED], [RURAL], [IMMIGRANT])
  ) u
where
    u.[b] = 'Yes'

select [Key], [REALTIONSHIP], [DEMO] = cast('DISABLED' as varchar(20)) 
from Table1 
where [DISABLED] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('LIMITED' as varchar(20)) 
from Table1 
where [LIMITED] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('RURAL' as varchar(20)) 
from Table1 
where [RURAL] = 'Yes'
union
select [Key], [REALTIONSHIP], [DEMO] = cast('IMMIGRANT' as varchar(20)) 
from Table1 
where [IMMIGRANT] = 'Yes'
