In Crystal Reports, what is the correct way of linking a parament subreport to the main report so the subreport does not run separately for each row of the main report?
The subquery (called paragon on the screenshot) is placed in a Group Header and it's linked to the main report with two parameters:
The main report returns about 300 records and watching it run, I can see that the subreport is run separately for every returned record which takes a fair bit of time.
If I run the SQL, which looks something like, directly say from PowerPivot,
with cte (select membership_info
from server1)
select appointment_info, cte.membership_info
from server 2
it only takes a few seconds to run. Unfortunately, because of REASONS (completely beyond my control) the query has to be run and formatted using Crystal Reports and it's scheduled to be run at regular intervals.
is there a better way of linking the report to the subreport, so the subreport executes only once?
Subreport should fire once for each instance of a section you place it in (GH3 in your case). There is no way around that. But there are alternative approaches...
For example, why not simply join the membership and appointment tables in the main report? You can suppress the appointments detail if all you need is some summary info...

Similarly i have an requirement that, in one main excel report should have tittle only, and then need to call two independent queries and display the results below the tittle. Just need to send counts of records from both queries to main report.
I don't want to repeat the results just display once.
Thats basically what subreports are for. You can create one JRXML-report which contains two child (sub)reports. Each subreport can have its own Query.
PS : The detail Band is rendered once per Resultset. So maybe it is enought to use this.
Maybe someone can Help me find the right technique.
I have a number of Crystal Reports that I am updating (Crystal Reports XI).
These reports each have an SQL Function associated with each that either retrieves records from the database (if any meet criteria) or returns an Empty Dataset (which happens daily).
These are executed in a batch process and directs the output to a PDF file which is emailed to users.
I am relatively new to Crystal Reports.
I am attempting to use a common SubReport to format/gather data for the Headers/Footers used in these documents. So far - most of this is working as I would expect. This allows me to use a single SubReport to generate the same Header/Footer in multiple reports (at least that's my goal).
However - I added a Report Footer section to the Main Report - my plan with this was to generate a Report Footer that would contain the following information:
A static Text Message that reads " --- END OF DOCUMENT ---"
The Report Title of the "Main Report"
The Date and Time that the Document was generated and Total Number of pages.
Sounds pretty simple.
So SubReport is named: "END-OF-DOCUMENT-SUBREPORT"
I used the "Special Fields" Data Date, Data Time, & Page N of M
Since the "Special Field" Report Title is returning me the "END-OF-DOCUMENT-SUBREPORT" value I used a Parameter field to pass the Report Title value from the Main Report to the SubReport.
This all works fine - HOWEVER - with the addition of the Linked Parameter Field from the Main to the SubReport - when I execute the report to generate the document - the SubReport ends up showing a blank Report Footer - that I can click on to reveal the "END-OF-DOCUMENT-SUBREPORT" in another Tab.
Without the Parameter field - it didn't do this and the information from the SubReport appeared on the last page of the document.
Is this a standard behavior of Crystal?
I'm not sure how to Suppress the "Drill Down" feature and still display the Report Section.
You can pass variable between you Main Report and sub Report. You can also create variable and assigned them to a sub report. As aMazing mention, creating Header and Report Footer sub report is not common. It is even messy. If you want something generic, I will create a report template that you will use in the future.
Have a good day!
I have a crystal report that takes only about 1/3rd of the report space.
I have field read from the database which is an integer value.
I wish to print this report number of times as read from the database on the same page.
Any idea on how this can be achieved?
I can only use crystal report for achieving this.
Thanks in advance.
You can create another report and add your current report as a subreport multiple times
Lan is correct, build another report and add your current report as a subreport.
Here's the trick:
On your main report, have it make a list of all of the items that
you'd like to run the sub-report on.
On your sub-report, add a parameter called "itemNumber" or something like that. Then change your Subreport Links so the new "itemNumber" parameter is linked to the item on your top level report.
Now hide the field on the main report but leave the
subreport visible.!
This should make your report run for all items at one time.
In this case you can create a table with the maximum number of prints you will ever use. For example if you think you might need to print the report 100 times your table should contain records from 1 to 100. So lets assume this is the case- create a table , name it Copies and add a field CopyNo. Create a 100 records and set CopyNo from 1 to 100. Create the a main report based on Copies table - the record selection formula will be something like :
Copies.CopyNo<=#NumberOfCopies
#NumberOfCopies is a parameter , which you can set in order to control the printed copies. Create your actual report as a subreport and place it in the details section of the main report. When you run the report it will ask you for the number of copies and when you insert it, will print the same subreport as many times as the number you provide.
Crystal Reports is used to create templates for another application in my case. A value is passed from the other application to a specific table, which I can then, in crystal, use with inner joins to other tables to specify the values on the rest of the report.
This has worked well in situations where I have not being using subreports. In my main report, I have 4 tables inner joined, and they are correctly being passed a certain value from this program.
My problem lies with attempting to create a coverpage for this particular report. I needed a detail section on the coverpage, so I looked to creating a subreport on the report header of the main report. I used the same tables in the subreport itself with the same inner joins. It receives extra values. This is the exact inner join design with the same tables from the main report, yet it is showing different results.
Does anyone have a solution to this? I am particularly new to crystal reports, and have just avoided subreports to avoid deeper complication. I believe I may just be able to pass the criteria value from the main report through a shared variable or parameter as an alternative to my current attempt, but I am not sure how.
Thanks.
It sounds like you are taking the right approach by using a subreport. You did add the parameter to the subreport and linked it through from the main report?
I suggest you view the SQL query for both the main report and subreport to identify the discrepancy.
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
