I use the following code to pass parameters into a CR
// Reuse myDiscreteValue, and assign second country
myParam = new ParameterField();
myDiscreteValue = new ParameterDiscreteValue();
myParam.Name = "#toDate";
myDiscreteValue.Value = RmtUtility.Utility.DisplayDate(toDate);
myParam.CurrentValues.Add(myDiscreteValue);
myParams.Add(myParam);
I get an error message "Missing Parameter Value" when I tried to export the document using CR Option.
:(
Try clearing and then setting the values of the parameters within the Report object.
Something like this:
ParameterDiscreteValue paramDV = new ParameterDiscreteValue();
paramDV.Value = RmtUtility.Utility.DisplayDate(toDate);
report.ParameterFields["#toDate"].CurrentValues.Clear();
report.ParameterFields["#toDate"].DefaultValues.Clear();
report.ParameterFields["#toDate"].CurrentValues.Add(paramDV);
Note: report being your Crystal Report Document

I am using jasper reports and want to give user to select the db name as input control and want to use that in query.
tool used is ireport /jasper soft studio 6.x
Got the solution for above question I used list of input control and then used the parameter value as
$P!{parametername}
Same as usage of table name as parameter/input control in jasper.
If I am understanding correctly, following code might help you.
Ofcourse "foo DB" and "baz DB" should have same tables.
Connection conn;
// Change the DB depend on input value.
if (userInput.equals("foo")){
conn = DriverManager.getConnection("jdbc:mysql://localhost/foo", "user", "password");
}
else if (userInput.equals("baz")){
conn = DriverManager.getConnection("jdbc:mysql://localhost/baz", "user", "password");
}
else{
// error
}
JasperReport jasper = (JasperReport)JRLoader.loadObject(your_jasper_filePath);
Map paramMap = new HashMap();
paramMap.put("param1", "some_param1");
paramMap.put("param2", "some_param2");
JasperPrint print = JasperFillManager.fillReport(jasper, paramMap, conn);
JasperExportManager.exportReportToPdfFile(print, PdfPath);
i have a code like this for passing parameter filed value into crystal report.
Dim projectreportds As New ProjectRptnew -**this s dataset name**
If ds.Tables.Count > 0 Then
projectreportds.Tables(0).Merge(ds.Tables(0))
Dim rpt As New ProjectReportNew-**this s report name**
rpt.SetParameterValue("ExhbitionName", cmbExhibition.Text)
Dim objrpt As New frmrptengine(AppPath & "\reports\ProjectReportNew.rpt", projectreportds)
objrpt.ShowDialog()
End If
but if am running this code am asking parameter value.what changes i have to make in my code..
Try this:
Set App = CreateObject("CrystalRuntime.Application")
report= "c:\report.rpt"
Set rep = app.OpenReport(report)
For i = 1 To rpt.Database.Tables.Count
Print rpt.Database.Tables(i).name
If rpt.Database.Tables(i).name = "YOUR_TABLE_NAME" Then
//first table login
rpt.Database.Tables(i).SetLogonInfo "YOUR_SERVER_NAME","YOUR_DATABASE_PATH",Username.Abbreviated,Password
Else
//second table login
rpt.Database.Tables(i).SetLogonInfo "YOUR_SERVER_NAME","YOUR_DATABASE_PATH",Username.Abbreviated,Password
End If
Next
YOUR_TABLE_NAME= name of the table, you can find it under "Database" menù, "Database Expert" ->"Selected Tables"
YOUR_SERVER_NAME= the server name of source database
YOUR_DATABASE_PATH= the complete path of the source database
Username.Abbreviated= the username to access database
Password= password of "Username.Abbreviated" to access database
and to pass parameter field:
rpt.ParameterFields(1).AddCurrentValue (num)
num is my parameter field
I am developing the Invoice printing System using the Jasper report, Now I have can print the report but it will take 2000ms to load the report, also 2000ms take to start the printing,
These are I am using the JAR FILES,
commons-beanutils-1.4
commons-digester-1.7
commons-logging-1.0.3
commons-beanutils-1.4
groovy-all-1.7.5
batik-all-1.7
barcode4j-2.1
itextpdf-5.1.0
jasperreports-6.0.3
xercesImpl-2.11.0
xml-apis-ext-1.3.04
preparedStatement = conn.prepareStatement(sqlString);
resultSet = preparedStatement.executeQuery();
if (resultSet.next()) {
HashMap<String, Object> hm = new HashMap<>();
JasperDesign jasperDesign = JRXmlLoader.load(new File(
"C:/Invoice/Invoice.jrxml"));
JRDesignQuery designQuery = new JRDesignQuery();
designQuery.setText(sqlString);
jasperDesign.setQuery(designQuery);
JasperReport jasperReport = JasperCompileManager
.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(
jasperReport, null, conn);
for (int i = 0; i < copies; i++) {
JasperPrintManager.printReport(jasperPrint, false);
}
JasperViewer.viewReport(jasperPrint);
The above code I used to print the report but, getting too much time to load the report. Please suggest my fault and some other idea...
I guess the SQL query could be the problem. Have you tried executing it in a sql query tool and check how long it runs? Optimizing it should yield a performance win.
You are also running the query twice: before the report and when you are filling it via the JasperFillManager.fillReport() call.
If there are no specific reasons to check wheter the query contains any records, I would recommand to let JasperReports handle the query and the case that no record is found. You can determine a specific behaviour in that case via the "When No Data Type" property in the reportdesign.
I would like to create a table in my Jasper Report.
This could be done (and it is done :-) ) in iReport, but the content of the table (for example names of the columns) are changing, so I would like to create the report solely from JAVA code (by not using jrxml files).
How is it possible?
So far, this is what I have done (the main parts only):
//table component
final StandardTable table = new StandardTable();
final StandardColumn col1 = new StandardColumn();
final DesignCell col1Header = new DesignCell();
final JRDesignStaticText textElement = new JRDesignStaticText();
col1Header.addElement(textElement);
col1.setDetailCell(col1Header);
table.addColumn(col1);
/datasource
final JRDesignDatasetParameter param = new JRDesignDatasetParameter();
param.setName("REPORT_DATA_SOURCE");
final JRDesignExpression exp = new JRDesignExpression("$P{REPORT_DATA_SOURCE}");
param.setExpression(exp);
//datasetrun
final JRDesignDatasetRun drs = new JRDesignDatasetRun();
table.setDatasetRun(drs);
drs.addParameter( param );
How to continue?
Thank you,
krisy
In case anyone stumbles upon the same problem (and for future myself :-) ) here is how to continue the code above, to add a table element to the summary of the report:
//create reportElement (inside componentelement)
JRDesignComponentElement reportElem = new JRDesignComponentElement();
//reportElem.setKey("table");
reportElem.setComponentKey(new ComponentKey("http://jasperreports.sourceforge.net/jasperreports/components", "jr", "table"));
reportElem.setComponent(table);
reportElem.setHeight(100);
reportElem.setWidth(100);
//add to summary
jRSummary.addElement(reportElem);
(the hard part was to find out how to create the ComponentKey object)
Note: in order to use the table, the subdataset element needs to be created as well.
For htmlComponent the ComponentKey should be:
new ComponentKey("http://jasperreports.sourceforge.net/htmlcomponent", "jr",
"html");
Well I have a Cyrstal report which has 4 sub reports on and it is linked through an ItemID column and a Culture, so it has a parameter value "?Pm-ItemID" and "?Pm-Culture" now i'm using DataSet to load the data to the Crystal Report's datasource, when I run the report its giving me an error which was an asking parameter field was not suplied, so i think my question would be what am I going to pass to those ParameterFields?
here's an idea.
ReportDocument myreport = new ReportDocument();
myreport.Load("C:\MyReport.rpt");
DataSet ds = GenerateReportData();
myreport.SetDataSource(ds);
//Loop through each to Load the DataSet
for (int i = 0; i < myreport.Subreports.Count; i++)
{
ReportDocument subreport = myreport.SubReports[i];
DataSet subds = GenerateReportData(subreport.name)
subreport.SetDataSource(subds);
}
//I can see that there's a parameterfields in myreport.ParameterFields
//As I look through inside it there are 8 ParameterFields repeating Pm-ItemID and Pm-Culture
foreach (ParameterField pf in myreport.ParameterFields)
{
myreport.SetParameterValue(pf.Name, Value???);
}
Well, I see what's wrong.
ReportDocument subreport = myreport.SubReports[i];
DataSet subds = GenerateReportData(subreport.name)
subreport.SetDataSource(subds);
should not be done this way, it should be
DataSet subds = GenerateReportData(subreport.name)
myreport.SubReports[i].SetDataSource(subds);
I don't know about Crystal, but in SSRS it works like this:
1) create a subreport and create some parameters
2) create the main report, put there the subreport and in the properties you can specify what to bind to the subreport's parameters
Conclusion: I don't think this is supposed to be set in code, rather report designer.
