一. 摘要
Oracle Report Builder开发的字符模式的报表，成为系统报表
- 优点
- 采用图形化的开发方式，比较直观
- 有功能强大的向导
- 对比较复杂格式的报表也不要通过太多代码来实现
- 最终结果以一个独立的文件的形式展示，比较容易传递
- 缺点
- 很难转成execel格式文件
- 虽然有布局编辑器，但是实际编写过程中，其宽度和位置的拖动比较繁琐
通过在数据库中直接产生HTML格式的文件，成为HMTL报表
- 优点
- 输出的文件，可以直接另存为execel或者word格式
- 布局简单
- 在调试时，只需数据库编译即可，不要像rdf文件上传至server
- 缺点
- 程序包方式的开发，没有可视化界面
- 对比较复杂格式的报表需要较大的代码量
- 输出的为HTML标记，产生的文件会比较大
HTML报表的实现方式
- 通过在数据库端调用过程fnd_file.put_line生产文件
- 在生成文件过程中通过动态加入html标记实现文件的格式化
- html文件本身可以直接转换为excel形式或者word当个事
二、案例
需求：客户要求以HTML的形式呈现供应商信息
1. 建立Procedure， 以输出HTML标记
2. 建立Program Execuable, 设定程式为bxj_html_invoice_report.main
3. 建立Concurrent Program并发程式，输出方式为HTML
4. 运行程式并测试http://i.cnblogs.com/EditPosts.aspx?opt=1
Step1. 建立Procedure， 以输出HTML标记
1 procedure bxj_html_invoice_report(Errbuf Out Varchar2, Retcode Out Number) is 2 cursor cur_invoice is 3 select pv.VENDOR_NAME, 4 aiv.invoice_num, 5 aiv.invoice_date, 6 aiv.invoice_amount, 7 aiv.invoice_currency_code 8 from Ap_Invoices_All aiv, po.po_vendors pv 9 where rownum <= 100; 10 l_invoice cur_invoice%rowtype; 11 begin 12 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘<html><head>‘); 13 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘<style type="text/css">‘); 14 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘* { margin: 0; padding: 0;}‘); 15 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘.all { width: 100%; border: 1px solid#000000;}‘); 16 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘.title {width: 99%; }‘); 17 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘table {width: 100%; border: 1px solid#FF00FF; border-collapse: collapse; table-layout:fixed; }‘); 18 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘table tr th { border: 1px solid #FF00FF;overflow: hidden; word-break: break-all; text-overflow: ellipsis; white-space: nowrap;}‘); 19 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘table tr td { border: 1px solid #FF00FF;overflow: hidden; /*word-wrap: break-word; 内容将在边界内换行*/word-break: break-all;‘); 20 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘text-overflow: ellipsis; white-space:nowrap;}‘); 21 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘.content {width: 100%; height: 80%;overflow: scroll; }‘); 22 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘.content div { width: 100%; }</style>‘); 23 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘</head><body><div class="all">‘); 24 --表头 25 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<div class="title"><table><tr>‘); 26 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:30%">VENDOR NAME</th>‘); 27 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:20%">INVOICE Number</th>‘); 28 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:20%">INVOICE Date</th>‘); 29 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:10%">INVOICE Amount</th>‘); 30 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:10%">Currency Code</th>‘); 31 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<thstyle="width:10%">Note</th> ‘); 32 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘</tr></table></div>‘); 33 --内容 34 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<div class="content"><div><table>‘); 35 open cur_invoice; 36 loop 37 fetch cur_invoice 38 into l_invoice; 39 exit when cur_invoice%notfound; 40 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘<tr>‘); 41 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:30%">‘ || l_invoice.VENDOR_NAME || ‘</td>‘); 42 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:20%">‘ || l_invoice.invoice_num || ‘</td>‘); 43 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:20%">‘ || l_invoice.invoice_date || ‘</td>‘); 44 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:10%">‘ || l_invoice.invoice_amount || ‘</td>‘); 45 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:10%">‘ || l_invoice.invoice_currency_code || ‘</td>‘); 46 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT,‘<td style="width:10%"> </td>‘); 47 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘</tr>‘); 48 end loop; 49 close cur_invoice; 50 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘</table></div></div>‘); 51 apps.Fnd_File.Put_line(apps.FND_FILE.OUTPUT, ‘</body></HTML>‘); 52 end; 53 end cux_html_invoice_report;
Step2. 建立Program Execuable, 设定程式为bxj_html_invoice_report.main
Step3. 建立Concurrent Program并发程式，注意输出方式HTML，其他设定与普通CP无太大差异
三、案例测试
Test1. 调用Concurrent Program并发程式，输出方式为HTML，查看输出
