数据库输出HTML格式报表的测试
在使用前需要配置apache的连接, 这样在调用过程的时候, 系统直接将生成的html输出到WEB;
--配置apache连接:
如安装在D:\system\https 下, D:\system\https\Apache\modplsql\conf\dads.conf文件. 设置为 :
<Location /ss>
SetHandler pls_handler
Order deny,allow
Allow from all
AllowOverride None
PlsqlDatabaseUsername dinya
PlsqlDatabasePassword dinya
PlsqlDatabaseConnectString dinya:1521:ora10g
PlsqlAuthenticationMode Basic
</Location>
当然对数据库的连接必须有效, 具体请见相关的设置文档. 重起Apache服务.
--创建测试包:

type c_sql is ref cursor;

procedure html_header(p_title in varchar2);

编译没有错误后, 使用http://dinya:7777/ss/cux_html_report.main 即可查看报表.
如果在main过程中使用 owa_util.mime_header(clearcase/" target="_blank" >ccontent_type => 'application/vnd.ms-excel'); 可以直接将数据生成到Excel中.
如:
procedure main as
begin
owa_util.mime_header(ccontent_type => 'application/vnd.ms-excel');
html_header('我的测试报表');
需要使用的话, 可以根据需要修改上面的程序.
