I am new to JasperReports, basically I want to put a subreport in a mainreport
The problem is that I put the sub report in the Detail band, so when I query a database that has multiple data the subreport will always repeat itself multiple times when I output the report to a pdf. I want a report that does not repeat itself regardless of how many data I have in the database that i connect with
I have searched the Internet and the solutions is to add
new Boolean($V{REPORT_COUNT}.intValue()==1)
in the print when expression attribute of the subreport, that does solve a part of my problem due to the fact that now my subreport only prints once but it still leaves some blank pages after my subreport is displayed
So I assume it is still repeating itself but just doesn't print the data because of the expression that I added , people say that the nature of the detail band is supposed to work that way and that I shouldn't put the subreport in the detail band, but if I put it in some other band I get this error:
Error filling print... Subreport overflowed on a band that does not support overflow.
The error above will happen if I have a lot of data to the extent that it may take up more than a page.
How do remove those blank pages? If I am ask to not put it in a detail band then what should I do? or what solution are there?
The Detail band will be generated as many times as the number of records you have in your main dataSet(populated by the top-level query).
If you want to keep the subreport in the Detail band, which is normal by the way, you can do one of these things:
either have a dummy query that returns only one record, so that the Detail band generates only once. Then, pass the report connection to your subreport. You may have done that already. This way you can run your query independently of the main report.
or leave the report as-is and add your printWhen expression ($V{REPORT_COUNT}.intValue()==1) directly on the Detail band, not on the subreport. Please note that this is just an ugly hack that may affect the report performance. Your main query still returns a lot of data that you don't use so you should consider the other options.
If you can move the subreport out of the Detail band, place it in a band that allows overflow like Title or Summary band. Then:
have your main dataSet's query empty so that no Detail band gets generated
set whenNoDataType="AllSectionsNoDetail" at the report level(in the <jasperReport> tag) so that all the other sections except the Detail get generated
exactly as in the first option above, pass the report connection to your subreport and work from there

I have a subreport included in the Detail band of the parent report. The SQL query in the parent report returns multiple rows. And so my subreport also gets displayed as many times as the records returned by parent SQL query. I want to display subreport only once irrespective of the records returned by SQL query in parent report. I have tried moving subreport to columnfooter section but then i get a "Subreport overflowed on a band that does not support overflow" error.
Any pointers to get it working will be really helpful.
Ok to start with: a subreport has a different Dataset (SQL query) then the parent report. If you use an query, the subreport is shown as many times as there are records as a result of the query. This is actually what it's meant for and that's the same as with parent reports.
What you want to achieve if I unerstand you correctly, is that you have the supreport outputted once and the main report outputted as many times as there are records returned. What I would suggest is:
Why don't you turn it around? Would solve all your problems and you use the programm as how it's meant to. You can do it like this:
Put the query that returns mulptiple record in a subreport, change layout so it matches your current parent report.
Put the data that should be displayed only once in you parent report Query (LIMIT bij 1 if it can return multiple records but you need the first). And put the necessary textfields etc. in the main report before or after the subreport.
Hope it helps! Let me know
I am using iReport 3.7.6 to create this report.
I have a report based off of an XML file. There is a 2-column master report and it has a detail band with a subreport.
I have a field called "Name" in the subreport. I want it to print at the top of every page. Or even at the top of every column. I have tried virtually everything I know how to do.
"Print When Detail Overflows" doesn't work, because this setting is in the detail.
I sure hope I don't need to create a subreport for every report break I want. I'll have like 4 or 5 subreports.
Is there some way to determine when the page has changed, and then use that event in a "Print When" expression?
Here is one solution, presuming the value does not change between pages:
Write a query for a subreport that obtains only the Name value.
Change the dimensions of the subreport to be as small as necessary.
Place the subreport in the page header band of the master report.
To answer your question accurately, more details (such as pictures of what you have versus what you want) would be helpful.
you can use pageCount variable which is implicitly available in jasper reports to know whether the page has changed or not.
I have place a subreport in my master report. I have my query like, for a application I have some 3 jobID. Based on this jobID I need to fetch the related data. I placed the jobID in the detail band and passed the same to the subreport as parameter.
Since the subreport is reporting only once in the master report, even though I have 3 jobID, it is display the first jobID data in the master report.
I need to get data for all the jobID of a application.
please see whether your sub report shows value for 3id if not then it cant appear data from three reports.
also place the subreport on the details band.
simple query with tree id returnce three row in the sub report is must. then only it will apear in the main report.
Note : if you place the report on the non repeating band. then that band only show the first comming data insted of showing 3 lines.
donot place sub report on title/pageheader/column heder with repeting value.
place only those sub report on this band which give only one value or one row
I am using iReport with JasperReports. I want to include multiple subreports that have unrelated sql queries. I would like to be able to put these all on one report.
The problem I am facing is that when I leave the master report sql query empty, none of my subreports have any data. There isn't really anything that the master report sends to the subreports since they are unrelated. Basically how do you throw multiple unrelated reports together into one report.
In order for the Detail Band to show, you will need to fill the main report query, even if its just a dummy query, like say:
SELECT 'a' FROM DUMMY
This will make the Detail band appear, and with it all the sub reports.
Otherwise, if you don't want to use the Detail Band, you have the option to view the other bands without using a query. From Edit menu, choose Report Properties, under More... tab, set the flag When no data to All Sections, no detail
