Passing parameters to JasperReports SQLl statement from Java

Question

I'm using JasperReports engine, and one of the reports gets data from database executing SQL statement. Is there a way to pass parameters to that query?

Thanks in advance!

Answer 1

First, create a new parameter in your report. Then insert the parameter in your query, for example:

SELECT name, department FROM employees WHERE employee_id = $P{employeeId}

Make sure your parameter types matches the data type of the columns in your database. Finally, simply pass your parameters to the JasperReports engine. An example would be:

parameters.put("employeeId", Long.valueOf(14309));
JasperRunManager.runReportToPdf(reportFile, parameters, connection);
