How to show number of rows on page and the total numbers of rows in report - jasper-reports

In JasperReport's report I have been showing data using table
In column footer I want to show total number of records per page
Page 1 Showing 25 records out of 65
Page 2 Showing 50 records out of 65
Page 3 Showing 15 records out of 65
I am using column count to show number of records per page but for total records in report what should I use
Page 1 Showing 25 records out of 25
Page 2 Showing 50 records out of 50
Page 3 Showing 15 records out of 65
Which variable should I use or any condition to be added?

You can easy solve this task with help of built-in variable $V{REPORT_COUNT} and custom variable.

The result
The output result generated in iReport via preview mode
How it works
I've add 3 textFields on Page Footer band:
1st one is for showing current page number. The expression is: "Page " + $V{PAGE_NUMBER} and the Evaluation Time is Now
2nd one is for showing count of rows on current page. The expression is: `"Showing " + $V{rowsOnPage} + " records out of "' and the Evaluation Time is Now
3rd one is for showing total rows in whole report. The expression is: $V{REPORT_COUNT} and the Evaluation Time is Report.
As you can see I've add custom variable rowsOnPage for counting number of rows on page.
The variable definition:
Expression: $V{rowsOnPage} + 1
Type: Integer
Initial value: 0
Reset type: Page
See details about:
Variables
Built-in variables in JasperReports Ultimate Guide

The variable "$V{REPORT_COUNT}" can solve your problem, use it at the evaluation time "report".

If you are using Ireport designing tool, then u can show total very easily by placing Page X of Y from palette.
Ireport 5.5 has palette under Window menu.

How do you calculate the median for a variable in iReport?

I am preparing a report in iReport, and I need to calculate the median of a field for a variable that will be used in a crosstab. I noticed there is no built in calculation type for median (just highest and lowest).
Is there any way to get the median or 50th percentile of a field in iReport?
There is no builtin median calculation in JasperReports.
A median can still be obtained by manually collecting the values in a list and then using Apache Commons Math to do the computation.
See the following example. The report also uses Apache Commons Lang to convert a wrapper array to a primitive array. To run the report, you will need to add commons-math3-x.y.z.jar and commons-lang3-x.y.jar to the classpath.

Jasper report with dynamic number of subreports [duplicate]

I have this set of records:
colors table.
color_group | color_name | color_no
Primary | Red | 1
Primary | Blue | 3
Primary | Yellow | 2
Secondary | Green | 8
Secondary | Violet | 1
Secondary | Orange | 7
Others | Pink | 6
Others | White | 4
Others | Black | 5
I want to generate report like this.
Primary
Red 1
Blue 3
Yellow 2
Secondary
Green 8
Violet 1
Orange 7
Others
Pink 6
White 5
Black 4
how can i display it like this in jasper report?
This is solved by using group on the color_group field and adding a groupHeader band to display its value.

Result
As per my knowledge this is the process to create and use group in iReport.
*Write desired query to fetch fields.
*Go to report name -> right click -> add report group ->
specify group name and group by object(in group-criteria) -> next ->
add group-header and footer if needed(in details) -> finish.
*Use this group where ever necessary(by using 'print when group' expression
as created group).

Print When Expression to print only the last element in the group

I have following data set in oracle table and want to generate CSV file from that data.
My data
CaseID Amount
1000 10
1000 20
1000 50
2000 30
2000 10
3000 30
3000 20
3000 20
It is necessary to show the following output from above data.
Required Output
CaseID Amount Aggregate
1000 10
1000 20
1000 50 80
2000 30
2000 10 40
3000 30
3000 20
3000 20 70
Aggregate column is populated by accumulating the sum of Amount according to caseID group.
Group summary should display on last element of the group. But not in the next row, should display in the same row and next column, that matching with the last element.
I tried with 'Print When Expression' for other scenarios, but unable to use with this scenario. Also I have find similar questions, but not cater with this requirement. So would like to know the possible solutions for this.
You can do something similar with evaluationTime="Auto". You can have a text element that shows the value on the last record in the group and is empty for other records. It's not the same as not printing the element at all, but you can't use the print when expression because it doesn't have delayed evaluation.
evaluationTime="Auto" uses the reset types of variables to decide the moment at which it reads the variable values. Each group has an automatically created count variable that resets with the group, and if you create a new variable that resets on each record you can use it to determine if the current record is the last record in the group.
The whole report would look something like this

Grouping records in JasperReports

I have a problem with JasperReports. I want to group the records depending on one specific column's value.
For example input data:
Name--email--PledgeType--amount
aaa--aa#yahoo.com--1--20.00
bbb--bb#yahoo.com--2--30.00
ccc--cc#gmai.com--1--35.00
ddd--dd#gmai.com--2-- 40.00
The output report will be grouped by the "PledgeType" value (1, 2, ... number):
Total for group one: 55.00
Name email amount
aaa aa#yahoo.com 20.00
ccc cc#gmai.com 35.00
------------------------------------
Total for group two: 70.00
Name email amount
bbb bb#yahoo.com 30.00
ddd dd#gmai.com 40.00
Can JasperReports solve this problem? how?
You can define grouping in JasperReports. JasperReports calculates the total for you, there is comfortable way to add groups and totals. Here an overview what you need to do in iReport.
To add the group
modify your query to order by pledgeType - JasperReports requires the data sorted according to your grouping.
right click on the report in the report inspector and choose Add Report Group.
Follow the wizard, set as group name PledgeType and choose Group by the following report object where you select the field PledgeType. Click next. Check Add the group header and click Finish.
To add the total
right click on variables in the report inspector and choose Add Variable.
In the properties panel choose this configuration: Variable class: BigDecimal, Calculation: Sum, ResetType: Group, ResetGroup PledgeType, Variable Expression: $F{amount}.
Drag & drop the variable into the group header in the report designer. Click on the field and change: Text field expression: "Total for group " + $F{PledgeType} + ": " + $V{totalPledge}, Expression Class: java.lang.String. Evaluation time: Group. Evaluation Group: PledgeType.
Info: The evaluation time decides when a variable gets evaluated, i.e. when the sum of the calculation will be shown. If you set it to group it means 'once the group processing is completed'.
Attached the generated report and the JRXML.
The JRXML is created with iReport 5.0 - however, if you follow the steps above it should work with JR v 2+

How can I pass sub-report value to main-report?

Here's the relation table
StudentName
Course
Marks
Peter
Bio
65
Peter
Chem
70
Peter
Music
80
David
Chem
50
How can I make something like the followings
Peter Total : 215
Subject : Bio - 65
Subject : Chem - 70
Subject : Music - 80
Peter Total : 50
Subject : Chem - 50
I would not use a subreport for this as this can be achieved in a simpler way: You can utilize Report groups and variables to achieve this. Make sure that the data is sorted accordingly to the output.
Preparation
Create a report group based on StudentName. Right Click in iReport in the report inspector on the report and select Add Report group. Follow the wizard, give it a name (e.g. Student), select field StudentName as group expression, add header but no footer.
Create a variable that holds the total for a student. Right Click in iReport in the report inspector on Variables and select Add Variable. In the properties panel configure as follows: Name: totalMarkByStudent, Variable Class: java.lang.Long, Calculation: Sum, Reset Type: Group, Reset Group: Student, Variable Expression: $F{Marks}. Leave the rest to its default values.
Report Design
Drag and drop the Field StudentName from the report inspector into the report designer into the Student group header band. There will be a popup asking what kind of value shall be displayed, select The field value and click Ok.
Drag and drop the Variable totalMarksByStudent from the report inspector into the report designer into the Student group header band. Click on the text field and modify following settings in the properties panel:
Width: 200 (to allow more space)
Text field expression: "Total : " + $V{totalMarkByStudent}
Expression Class: java.lang.String
Evaluation Time: Group (meaning that the value gets evaluated once the processing of the group is finished)
Evaluation Group: Student
Drag and drop the fields Course and Marks from the report inspector into the detail band in the report designer. Right click on the course field and select Edit Expression. CHange the expression to "Subject : " + $F{Course} and click on Apply.
With this configuration you achieve a report output as in the image below.

If you use a subreport instead
I assume that the subreport is paraemterized with the student id shows the data for a given student. The main report shows the field StudentName and the subreport in the detail panel.
Create a variable total in the subreport that calculates the total for the student.
Create a variable totalByStudent in the main report with calculation type set to System.
Click on the subreport and in the properties panel click on Return values. Click Add and select: Subreport variable: total, Local Destination Variable: totalByStudent, rest leave to default. Click on Ok.
Drag and drop the variable totalByStudent into the detail band. Select it and in the Properties panel set Evaluation time to Band. The output will be the same as shown above.
I recommend to use the approach with report group and variable as it reduces the complexity of the report, as well as performance for this way would be better.
