I ask you because I am a novice on this software and I need advice. I have to create a planning document with jaspersoft studio, the type of expected response is for example: Zoning A: yes
Zoning b: no. To have this type of response is it necessary to create a boolean parameter?
Or do I have to create a boolean expression. What is a text field? Thanking you for your help.

I'm running into a bit of a problem when trying to lookup/create a report showing characteristic value descriptions.
My issue is that some of our characteristics are created with Datatype = NUM (via tcode CT04) and I can easily find these in table CAWN but I don't find the actual value description which is usually present in CAWNT.
Any idea why and/or if SAP ERP stores the value description in another table when Datatype = NUM ?
(FYI - there's no problem when Datatype = CHAR)

Dynamic parameter of table name in Jasper [duplicate]
(1 answer)
Closed 3 years ago.
I have this problem with the JasperServer report I'm trying to create:
I have several db tables, named using a name and a date like this:
TABLE_NAME_YYYYMMDD
I want to be able to choose (and do a select from) the table which corresponds to the date submitted by the user from an ordinary Date input control.
I've tried creating a variable (called TABLE_NAME) which uses Java expressions for parsing the date like:
"MY_TABLE_" + new SimpleDateFormat("yyyyMMdd").format($P{RUN_DATE})
and when I print the value of the variable in the report it looks correct. But then I tried using that variable name in the SQL query like:
SELECT column1,column2.. from $V{TABLE_NAME}
but when I tried running the report in Jaspersoft Studio I got this Exception:
net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.JRException: Error executing SQL statement for: my_report_x.
at com.jaspersoft.studio.editor.preview.view.control.ReportControler.fillReport(ReportControler.java:511)
at com.jaspersoft.studio.editor.preview.view.control.ReportControler.access$20(ReportControler.java:486)
So it doesn't seem to be working.
I read about the case when the whole table name can be specified in a parameter, and you're supposed to use:
$P!{tableName}
First I tried using that '!' with the variable name like:
..from $V!{TABLE_NAME}
but I got the same Exception.
Then I tried creating a new parameter instead, where "Is For Prompting" is Not checked, and as default value expression I put the same expression as I used in my variable:
"MY_TABLE_" + new SimpleDateFormat("yyyyMMdd").format($P{RUN_DATE})
but I still get the same error when I try to run the report in Jaspersoft Studio.
Does anyone know if there is a way to solve this? -Preferably a way that doesn't take several days to implement since I don't have that time.
I'm using Jaspersoft Studio 6.1.1.final and running the reports in JasperServer 5.5.0.
You should be able to get this to work by wrapping the whole of your FROM expression in the parameter e.g.
<parameter name="pTableName" class="java.lang.String">
<defaultValueExpression><![CDATA["from MY_TABLE_" + new SimpleDateFormat("yyyyMMdd").format($P{RUN_DATE})]]></defaultValueExpression>
</parameter>
And then using this in your SQL as a string literal:
SELECT column1,column2
$P!{pTableName}
WHERE 1 = 1
I just found out what I did wrong.
I admit it was rather stupid, but I only tried running the report in the Preview mode in Jaspersoft Studio. That's when I got the SQL error.
But I assume that the Preview mode does not support dynamic decisions about which table to read from, because when I ignored the Preview errors and published the report to JasperServer, I actually could run it there!
I ended up using the $P!{TABLE_NAME} parameter where the value is what I tried earlier:
"MY_TABLE_" + new SimpleDateFormat("yyyyMMdd").format($P{RUN_DATE})
I can print as much as possible of my SQL here (meaning that I have to replace names since this is a work report) if you want to see it:
select c.column1,c.column2, h.column3 from $P!{TABLE_NAME} h, TABLE2 i, TABLE3 p, TABLE4 ca, TABLE5 c
where h.P_ID = p.P_ID and h.A_ID = ca.A_ID and ca.C_ID = c.C_ID and ca.SOME_VALUE = 1 and ca.OTHER_VALUE = 1
and i.I_ID=h.I_ID
and i.OTHER_ID=1
and h.VALUE_X > 0
order by c.VALUE_Y
So my advice to others who create Jasper reports is not to let yourselves get fooled by the fact that some things don't work in Preview mode. -That might just be the "preview limitations".
I'm trying too see how JasperReports Server gets the default value set in a report. I know how to set a default value in iReport, but I'm trying to come with a way to check for that value programmatically in Java.
In particular, I'm interested in a List of Values Single Value Radio Select, I am using a Resource Descriptor to get other Report data, but this seems to elude me. Any help at all would be greatly appreciated.
To set default value in case of null, you can do this
((!$F{field_name} == null) ? '0' : $F{field_name})
To get parameter type you can do
JRParameter[] params = jasperReport.getParameters();
for(JRParameter param : params) {
param.getName();
param.getDescription();
param.getDefaultValueExpression();
param.getNestedType(); // get parameter type that can be list, string
}
For detailed reference regarding Resource Descriptor you can check, they have given complete example http://jasperserver.sourceforge.net/docs/3-5-0/JasperServer-Web-Services-Guide.pdf
In SSRS 2008, I am trying to add a group expression based on the data containing the word "HOLD". Here is what I have currently.
=IIF(Fields!NOTE.Value.ToLowerInvariant().Contains("HOLD"), "Z-HOLD", Fields!DROPZONE.Value)
This is not working. Any ideas on what I have done wrong would be appreciated?
Simple mistake, you're converting the source string to a lower:
=IIF(Fields!NOTE.Value.ToLowerInvariant()
But then you're comparing it with an upper string:
.Contains("HOLD")
Try this:
=IIF(Fields!NOTE.Value.ToLowerInvariant().Contains("hold"), "Z-HOLD", Fields!DROPZONE.Value)
I have a SSRS "statement" type report that has general layout of text boxes and tables. For the main text box I want to let the user supply the value as a parameter so the text can be customized, i.e.
Parameters!MainText.Value = "Dear Mr.Doe, Here is your statement."
then I can set the text box value to be the value of the parameter:
=Parameters!MainText.Value
However, I need to be able to allow the incoming parameter value to include a dataset field, like so:
Parameters!MainText.Value = "Dear Mr.Doe, Here is your [Fields!RunDate.Value] statement"
so that my report output would look like:
"Dear Mr.Doe, Here is your November statement."
I know that you can define it to do this in the text box by supplying the static text and the field request, but I need SSRS to recognize that inside the parameter string there is a field request that needs to be escaped and bound.
Does anyone have any ideas for this? I am using SSRS 2008R2
Have you tried concatenating?
Parameters!MainText.Value = "Dear Mr.Doe, Here is your" & [Fields!RunDate.Value] & "statement"
There are a few dramatically different approaches. To know which is best for you will require more information:
Embedded code in the report. Probably the quickest to
implement would be embedded code in the report that returned the
parameter, but called String.Replace() appropriately to substitute
in dynamic values. You'll need to establish some code for the user for which strings will be replaced. Embedded code will get you access to many objects in the report. For example:
Public Function TestGlobals(ByVal s As String) As String
Return Report.Globals.ExecutionTime.ToString
End Function
will return the execution time. Other methods of accessing parameters for the report are shown here.
1.5 If this function is getting very large, look at using a custom assembly. Then you can have a better authoring experience with Visual Studio
Modify the XML. Depending on where you use
this, you could directly modify the .rdl/.rdlc XML.
Consider other tools, such as ReportBuilder. IF you need to give the user
more flexibility over report authoring, there are many tools built
specifically for this purpose, such as SSRS's Report Builder.
Here's another approach: Display the parameter string with the dataset value already filled in.
To do so: create a parameter named RunDate for example and set Default value to "get values from a query" and select the first dataset and value field (RunDate). Now the parameter will hold the RunDate field and you can use it elsewhere. Make this parameter hidden or internal and set the correct data type. e.g. Date/Time so you can format its value later.
Now create the second parameter which will hold the default text you want:
Parameters!MainText.Value = "Dear Mr.Doe, Here is your [Parameters!RunDate.Value] statement"
Not sure if this syntax works but you get the idea. You can also do formatting here e.g. only the month of a Datetime:
="Dear Mr.Doe, Here is your " & Format(Parameters!RunDate.Value, "MMMM") & " statement"
This approach uses only built-in methods and avoids the need for a parser so the user doesn't have to learn the syntax for it.
There is of course one drawback: the user has complete control over the parameter contents and can supply a value that doesn't match the report content - but that is also the case with the String Replace method.
And just for the sake of completeness there's also the simplistic option: append multiple parameters: create 2 parameters named MainTextBeforeRunDate and MainTextAfterRunDate.
The Textbox value expression becomes:
=Parameters!MainTextBeforeRunDate.Value & Fields!RunDate.Value & Parameters!MainTextAfterRunDate.Value.
This should explain itself. The simplest solution is often the best, but in this case I have my doubts. At least this makes sure your RunDate ends up in the final report text.
