I have a table component on a subreport being used with an independent data source (dataset) thats hooked onto the table object. The table has two columns, the following issues arise upon debugging:
Not all descriptions are loaded from the query I used
The second column is not showing the data at all
Is there any properties that I am missing?
Thank you
Kind reagrds

Jasperstudio reports require all parameter names to be the same.

I am using a DataGridPro component with different columns.
One one the columns is defined like this:
This issue is that I am trying to understand why the row is not available in the valueOptions prop of the column definition.
I would like to be able to populate the choices based on a list that is available on the row in another field.
But I get this error when I try to read the row:
Can you please help? The grid is populated with lots of rows coming from an api fetch.
Every other column is working fine accept this one.
Thank you.
I discovered that it was my bad. My column object was used twice with different parameters and so, yes, the row was not available for the second case.
There's a working report but I wan't to change the visibility of certain rows based on a completely new DB select that should be executed when the report is created.
It would be ideal, if I could load the values of said select in an array or a list and than simply trigger certain row's visibility by comparing e.g. the Row Id with the values in the array.
Im used to solve a problem like this by creating a View that delivers all the essential information in each row and is used as the main data source but I was wondering if there's an elegant way within crystal reports to solve such a task.
I can think of three ways to include control data like this into the report:
One row of config data: If you can arrange it that your config data query returns one row of data, it can be just added to the data sources of the main report, without any links to tables and views already there.
Config resultset for matching: If you have to match main data results to config values row by row, e.g. by the Row Id you mentioned, add this config query to your report and link it to the main data source accordingly. (You are probably already doing this within your pre-created view on database side.)
Query config by subreport: Most flexible but also time consuming option is to add a subreport in report header, add the config data query and arrange config results into (shared) variables as needed in the subreport. Shared variable values can be used in main report then to control section visibility.
Yes, one of the 3rd-party Crystal Reports UFLs (User Function Libraries) listed here provides such a function.
I am working in iReport 5.6.0. I am creating a report base utilizing a table and would like to build one or more options to hide a series of columns; effectively creating a master report which will allow users to have multiple report views based on a simple parameter selection. In theory, this should work. However, I am having a problem passing a parameter from the main report it the table (where I am would use it to activate the Column Print When property.
To be clear. I have created an outer parameter and an inner parameter. I have also successfully mapped the parameters. I know that the mapping is working as I have added a column to my table and placed the parameter within the data row so that I can visually evaluate it--this too, works. However, when I set the Column Print When property as
$P{parameter1_1}.equals("y")
or even
$P{parameter1_1}.equals('y')
and then preview the report, I receive the following error:
Parameter not found: Description: parameter1_1 Object: fx $P{parameter1_1}.equals("y")
I am evaluating JasperReports and Jaspersoft Studio for using in the company I work for and I am trying to build a report that contains information from 2 different databases.
I have 2 data adapters configured.
I've my research and found out that the only way to do so is to have either a list, table or subreport in a main report, but I still can't make it work.
I took the subreport approach, I have two reports that work separately, the main one executes this query in the sample DB
select 1 from ORDERS limit 10
The subreport runs this one in a Vertica database I own:
select 1 from my_schema.my_table limit 10
Both of them, as said, run separately.
So I go to the mainreport and add a SubReport element to the ColumnHeader band, then the wizard opens:
In the step 1 I select the subreport from the project
Second step is connection. I have these options:
Same JDBC conection
Use another connection
Use an empty data source
Use a JRDatasourceExpression
Don't use any connection.
The first and third ones are not what I want.
I tried to set the second one, but I could not find a way to select the data adapter that I have configured.
The last one doesn't work ( I get a message saying that my_schema doesn't exists, so I think that it is still trying to access the MainReport database).
Is there anyway I can make a subreport run a query in a different database/datasource from the main report?
I can summarize what I did if anyone has the same issue:
I made a proof of concept (therefore I do not have the code anymore), but I created a JRDataSource class using this tutorial and there I manually access the database and returned the rows. Then I use this as the datasource of my subreport/table.
Not as nice as I wanted, but it is possible
I guess this iReport article is also applicable to reports designed in jaspersoft studio; you just need to define the subreport connection parameter with the given expression.
Perhaps, you can ask for help from two parameters which defined in the master report by yourself. Such as:
$P{MySubreport} with type net.sf.jasperreport.engine.JasperReport;
$P{MyDatasource} with type net.sf.jasperreport.engine.JRDataSource;
Associate these two parameters to your subreport element respectively in attributes 'Expression' and 'Data Source Expression';
Please write your DataSource class that implements interface JRDataSource.
Then, in your servlet class, put your real parameter values(JasperReport for your subreport .jasper file, and your DataSource object) into a parameters Map object, and call JasperFillManager.fillReport().
I have a problem with a report, I pass a array of values to report (from Java code) and that information is loaded inside the report (that works fine). But, I need to pass that field values to a table component, I saw and I can pass parameters to table, but I need use the main field values inside of table component and print that data there (in table component).
I suppose you pass the data from java as datasource. You have to pass the datasource for the table in a parameter and run the report with a different datasource (may be empty if you don't need any data). Then set the table datasource to be that parameter and declare the fields in the subdataset of the table.
