Question

我有一个数据库，其中有值为零的字段。

我有jsp页面，我将编写sql查询并将sql查询作为参数发送到JasperReports

invoicePDF.jsp

<%
Integer id = (Integer) session.getAttribute("id");
System.out.println("id is:"+id);
String sql=null;
Connection conn = null;
String termsOfPmnt = (String)session.getAttribute("termsOfPmnt");
String dispThrough = (String)session.getAttribute("dispThrough");
try 
{
    Class.forName("com.mysql.jdbc.Driver");
    conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/marketing_database","root","root");
    sql="select company_profile.companyName, and_so_on  from company_profile,invoice,invoiceclient_details where invoice.CId='"+id+"' and invoiceclient_details.CId='"+id+"'";  
    ServletContext context = request.getServletContext(); 
    String fullPath = context.getRealPath("/WEB-INF/reports/report5.jrxml");
    InputStream input = new FileInputStream(new File(fullPath));
    JasperDesign jasperDesign = JRXmlLoader.load(input);

    JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

    HashMap<String,Object> map = new HashMap<String,Object>();
    map.put("sql",sql);
            byte[] bytes = JasperRunManager.runReportToPdf(jasperReport, map, conn);

            response.setContentType("application/pdf");
            response.setContentLength(bytes.length);
            ServletOutputStream outputStream = response.getOutputStream();
            outputStream.write(bytes, 0, bytes.length);
            outputStream.flush();
            outputStream.close();
            conn.close();
}
catch(Exception e) 
{e.printStackTrace();} 

        %>

和jasper报告代码如下

现在我的问题是，当JasperReports的报告打印出值时，它应该排除字段为零的行。

例如：

我有vat5，vat14，servicetax和cst.If vat5为零且vat14，servicetax和cst不为零然后它应该打印vat14，servicetax和cst.Likewise如果vat14为零并且vat5，servicetax，cst不为零然后它应该打印vat5，servicetax，cst，以便它在报告中将打印vat14排除为零

如何在JasperReports中将值等于零时从打印中排除文本字段
