Dynamic evaluation of columns

2003-01-02 12:20

Hi,

 

I have a requirment that needs to evaluate columns using values from result set and also a value that is out side the result set and is got from an XML file. This value is different for each row in the result set. How do I do it ? Can the fill manger help to fill these columns by doing the calculation in the javacode ?

 

Example.

 

Result set looks like.

------------------

 

code, processingTime

 

XML fields look like

--------------------

code, maxProcessingtime

 

Report looks like.

---------------

code, % deviation in processing.

-------------------------------------

 

%deviation in processing = (maxProcessingtime - processingTime) *100 / maxProcessingtime

 

 

Thanks in advance.

Hi,

 

There are at least two solutions fo this:

 

1) You create a custom data source for your report.

Check the "datasource" sample.

 

2) You use scriptlets. Check the "scriptlet" sample.

 

I'm sure you'll make your choice after fully

understanding both features of the library.

 

I hope this helps.

Teodor
