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;
