How to conditionally hide rows in Cognos report?

Tue, 07 Aug 2007 09:23:00 GMT

Data�Q?/span>

Estate	Block	Customer	Status
ALC	1	AAA
ALC	1	BBB	Settle
ALC	1	CCC
ALC	2	DDD	Settle
ALC	2	EEE

Requirement�Q?/span>Count records by estate, block, hide customer with status = ‘Settle’ when display.

Estate	Block	Customer	Status
ALC	1	AAA
ALC	1	CCC
Settled case:	1
Total case:	3
ALC	2	EEE
Settled case:	1
Total case:	2

It is a piece of cake that implementing this report in Crystal report, but it spent me much time in Cognos ReportNet—I can’t find out how to hide a whole row.

At first, I have tried to control visibility of the fields with conditional variable. But, there still existed a blank row though all the fields were hidden.

Estate	Block	Customer	Status
ALC	1	AAA
ALC	1	CCC

Settled case:	1
Total case:	3
ALC	2	EEE

Settled case:	1
Total case:	2

Another way I have tried is wrapping all fields with conditional block. The blank rows were still there, just with smaller height.

Finally, I gave up finding out which option could be used to hide the whole row. I have amended the SQL with COUNT(…) OVER (PARTITION BY …):

SELECT estate, block, customer, status, count(customer) over (partition by estate, block) as totalCase FROM table ORDER BY estate, block.

The retrieved data with the amended SQL:

Estate	Block	Customer	Status	totalCase
ALC	1	AAA		3
ALC	1	BBB	Settle	3
ALC	1	CCC		3
ALC	2	DDD	Settle	2
ALC	2	EEE		2

In the last step, A filter was added to the details in the report: status <> ‘Settle’, and the calculation of grouping area ‘Total Case’ was set to Average.

使用jasperReport的时候，在window�q�_��下面没问题，但部�|�到AIX下出现错误：(x��)
java.lang.NoClassDefFoundError: sun/awt/GraphicsEnvironment
最初以为是AIX上面的JDK的问题，一看没有rt.jar�Q�于是把�q�个文�g复制�?ji��n)过去，但是�q�是不行�Q�仍然报错：(x��)
java.lang.NoClassDefFoundError: sun/awt/X11GraphicsEnvironment
在网上找�?ji��n)一下，原来�q�个问题很普遍的。于是在生成报表的servlet里面加上�?br>System.setPorperty("java.awt.headless", "true");
但是仍然有错误：(x��)
java.lang.InternalError:Can't connect to X11 window server using '139.22.XX.XX:0,0' as the value of the DISPLAY variable.
在AIX中配�|�DISPLAY参数�Q�输入命令：(x��)
xhost + xxx.xx.xx.xxx
xxx.xx.xx.xxx是AIX的IP
搞定�?/p>
