2006 IR Open Dicussion Posted August 27, 2006 Share Posted August 27, 2006 By: fduo - fduo passing report parameter to a subdataset 2006-05-12 07:48 Hello, I am trying to pass a report parameter into a dataset. I was trying hard, but I didn't manged to get it working. Maybe someone sees a solution? Here is the Code of the dataset: - <subDataset name="SubDataset1" whenResourceMissingType="Null"> - <parameter name="laufnummer1" isForPrompting="false" class="java.lang.String"> - <defaultValueExpression> - <![CDATA[ (String)$P{REPORT_PARAMETERS_MAP}.get("laufnummer") ]]> </defaultValueExpression> </parameter> - <queryString language="sql"> - <![CDATA[ select r.id, a.agentur, r.clientstatus, decode(r.origin,null,'PortX','SCA') as Quelle from sumexii.t_dh_rech r, sumexii_security.t_allocation a where r.reserve3 = $P!{laufnummer1} and r.allocation = a.id ]]> </queryString> <field name="ID" class="java.math.BigDecimal" /> <field name="AGENTUR" class="java.lang.String" /> <field name="CLIENTSTATUS" class="java.lang.String" /> <field name="QUELLE" class="java.lang.String" /> </subDataset> - The Report parameter "laufnummer" should be passed to the dataset parameter "laufnummer1". My last try was with the REPORT_PARAMETERS_MAP. The Code of my report parameter: <parameter name="laufnummer" isForPrompting="true" class="java.lang.String"> - <defaultValueExpression> - <![CDATA[ "8923" ]]> </defaultValueExpression> </parameter> I would be really happy if someone could help me. Thank you for reading this. Regards Fabio By: Lucian Chirita - lucianc RE: passing report parameter to a subdataset 2006-05-16 01:42 Hello Report data is not visible inside subdataset expressions, subdatasets have completely separate data/name spaces. Therefore, when you use $P{REPORT_PARAMETERS_MAP} in an expression of a subdataset, you don't get the parameters map of the report but the parameters map of the subdataset (the name is indeed confusing and can lead to a wrong assumption). If you want to pass a report parameter to a subdataset, you have to use a <datasetParameter> element when instantiating the dataset (i.e. in your <datasetRun> element): <datasetRun subDataset="SubDataset1"> <datasetParameter name="laufnummer1"> <datasetParameterExpression><![CDATA[$P{laufnummer}]]></datasetParameterExpression> </datasetParameter> </datasetRun> Note that you can use the same for the subdataset parameter, it doesn't conflict with the report parameter. Take a look at the demo/sample/charts/SubDatasetChartReport.jrxml sample and at the crosstab samples, you can see there how to use subdataset parameters.
