Why Temporary Tables?

• To eliminate bad data • When aggregations or computations

are required• To do snapshots in time• To simplify processing• To “divide and conquer”

encValid = encounter + visitDate

create proc sp_genEncValid as

delete encValid

insert into encValid

Code structure

• XML representation

• Tokens and Parameters

• Invoking report window

• RunReport

• Backend functions

• Jasper/Ireport

XML Representation

Tokens and Parameters

• For substitution into queries

– $<var>

• For display

– XML elements

• for branching in code

– XML elements

– XML attributes

Tokens and Parameters

Invoking Report Window• Via menu

– Report window launched via menu.php

– $url = "runReport.php?rtype=" . $cat . "&reportNumber=" . $report["reportNumber”]…

• Via parameters page– Want tokens, but not parameters

– $url = “kickPoint.php?rtype=…”

• Using full parameter functionality– $url = "kickPoint.php?rtype=" . $cat . "&reportNumber=" . $report["reportNumber"] . "&lang=" . $lang . "&site=" . $site . "&patientStatus=" .

$report["patientStatus"] . "&treatmentStatus=" . $report["treatmentStatus"] . "&testType=" . $report["testType"] . "&groupLevel=" . $report["groupLevel"] . "&otherLevel=" . $report["otherLevel"] . "&menu=" . $report["menuSelection"];

runReport.php

DEBUG_FLAG = true displays much of the processing and queries

1. Reads parameters2. Special processing (Nastad, PEPFAR)3. Generates temp tables4. Generates graph5. Formats and displays report in separate

window6. Optionally generates Excel or PDF (Jasper)

Example with debugging

Backend[Addon] Functions

Used by runReport.php• genSemiAnnual(…)• applyCriteria(…)• buildSemiQuery(…)• BuildReportQuery(…)• drawPie/drawBar• generateQueryResult(…)• writeOutput(…)

Agenda

• Introduction

• Using Jasperreports

• Q&A

Introduction

• An Open source Java reporting tool

• http://jasperreports.sourceforge.net/

Using Jasperreports

• Design a report

• Integrate with TOMCAT

• Fill the report with data

• Export the report

Design a report

• Using iReports (layout, parameters for input, fields for output)

Design a report

• Generate a JRXML file.patientRpt.jrxml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report

Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

<jasperReport name="patientRpt"

….<parameter name="siteName" isForPrompting="true"

class="java.lang.String"/>…<field name=“total" class="java.lang.Integer"/>…

Design a report

• You can edit the JRXML files directly.

Integrate with TOMCAT

• reports.xml Add/Edit entries in reports.xml so we can get the right request of

TOMCAT.

For example, <report id="1591" patientStatus="62" treatmentStatus="1" testType="0">

<title lang="en">Active/Inactive Patients</title>

<title lang="fr">Patients actifs/inactifs</title>

…

<reportFile groupLevel="1" otherLevel="1">patientRpt.jasper</reportFile>


ReportViewerServlet serves to generate reports


• Get the parameter values from the POST/GET method.

ReportViewerServlet.javapublic void doPost(HttpServletRequest req, HttpServletResponse

resp) { … String lang = req.getParameter(PARAM_REPORT_LANG);String site = req.getParameter(PARAM_REPORT_SITE);…

Fill a report with data

• Get the database connection.For example,

Connection conn = DBUtils.getConnection(JNDI_DATA_SOURCE_NAME);


• Put values to parameters as we mentioned in the previous phases.

For example,

parameters.put(“siteName”,”Hopital Grace Children”);

• Especially queries.


• Using the connection and queries, we can get the data to fill the report.

JasperPrint jasperPrint =

JasperFillManager.fillReport(report, parameters, conn);

Export a report

• Jasperreport offers several formats.• CSV (JRCsvExporter)• PDF (JRPdfExporter)• XLS (JRXlsExporter)• XML (JRXmlExporter)• HTML (JRHtmlExporter)

Export a report

• Create an exporter, for example: JRHtmlExporter exporter = new JRHtmlExporter();

• Set parameters for the exporterexporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, response.getWriter());

• Export the report exporter.exportReport();

Export a report

Issues

• Visit (and other) dates

• Current status

• Correctness

• Formatting

• Consolidation
