[Creating a report using multiple data sources]

Solution with subreports:

Main DataSource based on second query. At this case main report contaion field $F{employee_id}
Make subreport with parameter $P{emp_id} and put subreport into detail section of main report. Subreport query like this: select last_name, salary from employees_db_1 where employee_id = ${emp_id}

Pass field of main report $F{employee_id} into subpreport as value of parameter $P{emp_id}.

...but... I think that subreport is over-powered solution of this problem. You can use one query

select db1.last_name, db1.salary from employees_db1 db1, employees_db2 db2 where employee_nick_name = $P{employee_nickname) and db2.employee_id = db1.employee_id

Subreport is not need at this case

[Having trouble aligning a subreport below text wrapped fields]

Set positionType on frame = Fix Relative To Top. Probably it's enouth for reesolving problem.

In addition you can set position for subreport = Fix Relative to bottom (I suppose it not need)

[why fist line result is in next line and last line result is missing?]

[How can shifted column-name in place of previous column name when column not contains any value]

You mast use Table component (jr:table) and set for column of table (jr:column) Column Print When expression like: $F{myFIeldStudentLastName} != null

[No data shown on subreport(Subreport using Java beans)]

1. Insert static text in title band of Charge_Type_Entries_Report (subreport). Is it will displaing?
2. Show values $P{Logo} and $P{0}. You can display it in main report.
 

[No data shown on subreport(Subreport using Java beans)]

1. Question: (Subreport using java beans)
jrxml: <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression> ???
I am don't see expression like 'new JRBeanCollecitionDataSource(collection)' for subreport.
2. Why subreport placed in title of main report? If you want display Entry in subreport then subreport must be placed in detail band whith dataSousrceExpression like new JRBeanCollectionDataSource($F{entries})
 

 

[Jasper report variable printing zero value]

Why you wrote at jaspersoft and stackoverflow the same wrong (uncorrect) question? You can't get right answer with this description.
You're wasting people's time. You must correct mistakes and show fields declarations. And show result with $F{source}.equals("Periodic Report")

[How to use conditional clause on a field in Jasper report to get values?]

Why 7 digids? You start only with 4 :) I guess that one of the possible values of $F{RACE_CODE} is "abcxyz" (you don't write example of data). Is it right? In this case you can use expression like this (java code example):

  public static void main(String[] args) {    String RACE_CODE = "abcxyz";       System.out.println(RACE_CODE.indexOf("abc") == -1 ? "0" : "1" + (RACE_CODE.indexOf("lmn") == -1 ? "0" : "1") + (RACE_CODE.indexOf("pqr") == -1 ? "0" : "1") + (RACE_CODE.indexOf("xyz") == -1 ? "0" : "1"));     }[/code]

 

[How to use conditional clause on a field in Jasper report to get values?]

$F{RACE_CODE} == 'abc' && $F{RACE_CODE} == 'xyz' always false. 
>>For one person there can be multiple RACE_CODE assigned to it.
Report field have only one value.

Question is unclear

[Dates.......]

1. I am don/t understand which reason make string parameters? You can use dates in query.
2. Order parameters sometimes is important. Place parameters in tree in order when dependent parameters after parent: date_from, date_to, from_date, to_date

Good luck

[Java Type mismatch Error within iReport]

OMG. What is it? Where author use collection?

[Java Type mismatch Error within iReport]

It is wrong (or not full) description of problem.

In first message you say about "Type mismatch: cannot convert from boolean to Object"

Now: "Type mismatch: cannot convert from long to Object."

Why you wrote about difference errors?

 

You don't show stacktrace. You don't show definition $F{invoiceHeader} in jrxml.

Telepaths are on vacation :)

 

Probably you can try change getInvoiceId() {return long} to getInvoiceId() {return Long}

 

But this is only an attempt to guess without seeing anything

Section "3.10 Subreports" is only brief introduction. This section is only sufficient for development in the style "firing with closed eyes" :)

[Why jaspersoft-studio-user-guide version 6.0 is incomplete?]

This documentation does not contain sections: crosstabs, lists, barcodes, groups, scriplets.

[Why incrementer runs twice?]

Hi, all.

JR versin 4.1.2

I have report with subreport.

From main report I pass parameter $P{myDataSource} = new MyClassDataSource(parent_object_from_main_report) into subreport.
Connection type for supreport = Don't pass data
MyClassDataSource implements JRDataSource interface  (In subreport displayed measures for object of main report per day. Search data and calculation runs at constructor)
Subreport have table, placed into summary band. Another bands was deleted in iReport. Subreport have only table.

measures is my special java-object  ValHoled.
For this object I write incrementer (some copypaste from net.sf.jasperreports.engine.fill.JRBigDecimalIncrementerFactory with little correction)
 

public class ValHoledIncrementerFactory implements JRExtendedIncrementerFactory {protected static final ValHoled ZERO = new ValHoled(0d);// blah blah blah            @Override            public Object increment(JRCalculable variable, Object expressionValue, AbstractValueProvider valueProvider)                    throws JRException {                               ValHoled value = ValHoled.duplicate((ValHoled)variable.getIncrementedValue());                ValHoled newValue = (ValHoled)expressionValue;                                               if (value == null || variable.isInitialized()) {                    value = ValHoled.duplicate(ValHoledIncrementerFactory.ZERO);                }                               if (newValue == null) {                    return value;                                   }                                              System.out.println("variable  ="+value.toString());                System.out.println("increment ="+newValue.toString());                                                  value.inc(newValue);                               System.out.println("result    ="+value.toString());                               new Exception().printStackTrace(System.out);                System.out.println();                return value;            }[/code]

Variable for sum declared only in Table DataSet 1. Subreport haven't fields and variables. All work only in Table DataSet.
The result is correct. Sum calculated as i need. But the questions. Why calculation summary value runs twice? Data source of subreport is empty IMHO (?).
I try pass JREmptyDataSource into subreport - the same result. Incrementer runs twice. This unnecessary work...
