ireportjasper-reports
i want to generate raport in ireport with existing database.
I have fields in strings $F{Price} and varible $V{SumPrice} in strings too, and need to convert to integer and sum whole column with field Price
Can in do it in ireport ?
I dont have access to the database.
i've been looking for the same problem and found the following:
http://jasperreports.sourceforge.net/sample.reference/xlsformula/index.html
you can set up the "detect cell type" to default true under export excel settings in ireport.
regards
It is quite easy. You can create group on product field and two variables on this group: for counting result sum and average sum. With help of built-in variable you can calculate and display the number of elements in this group.
This is working sample:

This sample takes CSV file as datasource. You can edit query - for getting data with SQL query.
The report design in iReport is:
The result will be (via preview in iReport):
You should read this article about using variables in JasperReports and this post about using groups in JasperReports.
Please remember that you should sort the data before group using. The quote from the post about grouping and sorting from the jasperforge.org:
In order to get an accurate data representation, the data in the data source should be already ordered according to the group expressions used in the report. One can either perform data sorting through the report query, or use the <sortField/> element.

You should set $V{SumPrice} "Variable class" property to
java.lang.Integerand "Variable Expression" property toInteger.parseInt($F{Price}).
