I am new to JasperReports and iReport designer. Now I have table in that I have a column salary . So I want to display the sum of all employees salary.
for that I took a table from pallet created dataset. It displays the table perfectly , in footer I want to display the sum of salary so I created a variable SalSum here is the properties of it,
class: java.math.BigDecimal
calculation: sum
ResetType:Report
Variable Exp: $F{salary}
The problem is , The sum of salary is not displaying and getting the discription as Variable not found:SalSum
and The table also displays 3 times in report how to solve this please help me anyone.
You can simply drag salary field to the footer area.Then it asks field value or result of aggregation function.You have to choose the second option and from there you select the Sum.That's it
the problem is that you might not use the correct tag for the sum,
<textFieldExpression>
you need to use for summing inside ireport.
here is a nice tutorial about how to implement it

am very new to jasper report
also I have tried looking at videos but can not seem to get this one concept
basically there is this main query which i have
select * from table
which is populated in the details area
however i want a second query
select count(*) from table where name = "tim"
and put the count on the footer
can this be done using jasper
any tutorial to this concept or guidance would be helpful
to sum up the details area should show all the data where as the footer should only show counts of a few things.
You can only have one DataSet (therefore query) for the report. In your case this is your main report select * from table, which seems to be working well.
You have two options for adding the information you want:
(and I would say the better option) is to add a variable $V{tim_count} which is configured as:
initial value 0
expression value "tim".equals($F{name}) ? 1 : 0"
calculation function sum
there are multiple ways to increment this variable, so I'll leave that with you. In the footer you would then add a text field with the $V{tim_count} variable as it's contents.
You can read about variables here https://community.jaspersoft.com/wiki/variables
You can add an object that has it's own DataSet:
Table
List
Subreport
You would then be able to add your query to that object and display it appropriately. As you can see, displaying a COUNT is not really the most appropriate way to do this.
Note - I don't suggest this way
I have made this tableau Worksheet. All columns are derived using calculated field. Based on resource I am calculating all attributes.
Please help me to add all values column wise in same worksheet .
I tried using "total" available in analytics pane but its not working in this case .
Thanks and Regards
The way this is set up, which each column being a calculated field, to sum them also requires a calculated field.
[ColumnA]+[ColumnB]+[ColumnC]+etc
Adding Totals to the table won't work in this case, as you have discovered.

I have aleady drag the field to the footer and header but in the aggregiate function i did not see sum fuction.
I have a fairly basic report that needs to show events with a total spend of >$200K OR event attendance >60ppl. The attendance portion is no problem, as it's a simple text field in the table. The expense spend is a field that has to be summed before it can be used, coming from a separate table with multiple entries per event. I have no problem doing this in a summary field dropped in the eventID header or even using a subreport and passing a shared variable to the main report. The problem I run into is that I cannot access this summary field in the report record selection to extract the either or records. Any idea how I can do this accurately?
Create a sql-expression field for total spending:
//{%total_spending}
(
SELECT sum(Amount)
FROM Meeting_Expenses
WHERE MeetingId=Meeting.Id
)
Use fields in record-selection formula:
{Meeting.actual_attendance}>60
AND {%total_spending}>200000
My data contains same value for a particular column.
My requirement is to merge the data rows for that particular column alone in detail band.
Is it possible in jasper reports.
please help.
Thanks & Regards,

You can make another group, other than Detail and set the Group Expression to the same field you want.
For example, if I want to group on Country, and show Cities in each country. In "Country" Group Expression. I would write:
$F{countryField}
