Jasper reports ireport与通用列组的交叉表？

我对JasperReports交叉表报告有问题

例如，我的数据当前采用以下格式：

| Date      | salesman      | area      | outlet    |
-----------------------------------------------------
| Date A    | Salesman A    | Area A    | Outlet A  |
| Date A    | Salesman A    | Area A    | Outlet B  |
| Date A    | Salesman A    | Area A    | Outlet C  |
| Date B    | Salesman B    | Area A    | Outlet A  |
| Date B    | Salesman B    | Area A    | Outlet D  |

Date    | Salesman      | Area      | Outlet 1 | Outlet 2 | Outlet 3 | etc
--------------------------------------------------------------------------
Date A  | Salesman A    | Area A    | Outlet A | Outlet B | Outlet C | ...
Date B  | Salesman B    | Area A    | Outlet A | Outlet D | .......  | ...

salesman      | category_1     | category_2     | category_3
------------------------------------------------------------
Salesman A    | Outlet A       | Outlet B       |
Salesman B    | Outlet A       | Outlet C       |

我需要以以下格式输出数据：

| Date      | salesman      | area      | outlet    |
-----------------------------------------------------
| Date A    | Salesman A    | Area A    | Outlet A  |
| Date A    | Salesman A    | Area A    | Outlet B  |
| Date A    | Salesman A    | Area A    | Outlet C  |
| Date B    | Salesman B    | Area A    | Outlet A  |
| Date B    | Salesman B    | Area A    | Outlet D  |

Date    | Salesman      | Area      | Outlet 1 | Outlet 2 | Outlet 3 | etc
--------------------------------------------------------------------------
Date A  | Salesman A    | Area A    | Outlet A | Outlet B | Outlet C | ...
Date B  | Salesman B    | Area A    | Outlet A | Outlet D | .......  | ...

salesman      | category_1     | category_2     | category_3
------------------------------------------------------------
Salesman A    | Outlet A       | Outlet B       |
Salesman B    | Outlet A       | Outlet C       |

创建交叉表时，我执行一个简单的查询

SELECT*fromtable

然后在交叉表向导中，我将日期设置为行组

我应该在列组中设置什么

我需要将列组设置为出口计数器，而不是出口值？测量值为出口

如何在iReport中执行此操作

之前，我考虑过使用postgreSQL交叉表查询

比如：

SELECT * FROM crosstabN(
    'SELECT salesman::text, date::date AS visit_date, outlet::text
    FROM table'
)

以上的输出格式如下：

| Date      | salesman      | area      | outlet    |
-----------------------------------------------------
| Date A    | Salesman A    | Area A    | Outlet A  |
| Date A    | Salesman A    | Area A    | Outlet B  |
| Date A    | Salesman A    | Area A    | Outlet C  |
| Date B    | Salesman B    | Area A    | Outlet A  |
| Date B    | Salesman B    | Area A    | Outlet D  |

Date    | Salesman      | Area      | Outlet 1 | Outlet 2 | Outlet 3 | etc
--------------------------------------------------------------------------
Date A  | Salesman A    | Area A    | Outlet A | Outlet B | Outlet C | ...
Date B  | Salesman B    | Area A    | Outlet A | Outlet D | .......  | ...

salesman      | category_1     | category_2     | category_3
------------------------------------------------------------
Salesman A    | Outlet A       | Outlet B       |
Salesman B    | Outlet A       | Outlet C       |

但我一直在用JasperReports实现查询

输出报告应与postgreSQL交叉表查询相同。

创建交叉表

salesman      | category_1     | category_2     | category_3
------------------------------------------------------------
Salesman A    | Outlet A       | Outlet B       |
Salesman B    | Outlet A       | Outlet C       |

您的数据选择应该是

salesman   |  category    |   value
-------------------------------------
Salesman A |  category_1  | Outlet A
Salesman B |  category_1  | Outlet A
Salesman A |  category_2  | Outlet B
Salesman B |  category_2  | Outlet C

行组将具有bucket表达式

<bucket class="java.lang.String">
    <bucketExpression><![CDATA[$F{salesman}]]></bucketExpression>
</bucket>

因此，您不应该尝试从数据库中获取交叉表结构，而应该是平面结构，其中交叉表列的名称是结果的一列。
是的，我知道我必须生成这样的数据，但我不知道如何获取其分区内的类别计数（category\N、category\N等）我刚刚发现了postgreSQL，我使用
row\u number
函数获取分区内当前行的编号。谢谢你的回答。
