#Jaspersoft studio query parameter not found zip file
The Zip file could be downloaded from here – LINK TO ZIP FILEĢ. I have created a working sample which could be simply deployed, and checked for the functionality and working.
Though could be run in iReport or JasperReports with default values hardcoded. Next and very important thing is that the cascading parameters could not be tested in iReport / JasperSoft Studio, this needs to be deployed on Jasper Server in order to check the correct functionality.Then we need to define the expression for parameters, and mind one thing that each of the parameter need to be of type if you want to enable multi- select.First of all you need to design a Jasper Report and identify the parameters to be cascaded.Now in order to achieve this in Jasper Reports we need to follow few steps. This enable for multi select also in the parameters. Parameter – Now this is the parameter selected by user and will be queried or looked in the field. Let me go one by one in explaining the components.įield – Now this is the field in the database upon which the find will be done each have separate filters but the boundaries of the parameter depends on the previous parameter.īefore getting into the setup of Cascading Parameters in Jasper Report there are few things which we need to know before hand – Usage of $X in the SQL Query used in the Where clause, which filters the data based on the selection. You can find these kind of filters in online shopping websites, wherein we can choose on various filters like if we want to buy the laptop first filter would be Laptop next filter would be the company chosen among the companies which sell Laptops, and then we chose for the specifications like processor, ram etc. Right, it could be used in parameters, or rather the filters which are dependent on each other.
Now where to implement this in Jasper Reports? Cascading, what does one mean by saying cascading, literally it means anything that resembles a waterfall or especially seeming to flow.
