用Perl从oracle导出百万级数据到excel excel 2007 可以存放1048576行、16384列的数据；excel 2003大概是65535行 我从oracle中导出30万行60列的数据到excel中花了约8分钟。
如果你还没有安装perl，按下面步骤
步骤：
1、下载并安装perl v5.8.8，可以使用perl －v查看是否安装成功
2、输入PPM命令打开perl的包管理器。找到并更新DBI
3、下载DBD-Oracle-1.17.zip解压到c:\perl 在命令行进入该目录执行： ppm install dbd-oracle.ppd 安装DBD－oracle；
4、安装 Excel 模块，如果你能联网，直接使用如下命令即可：
ppm install OLE::Storage_Lite
ppm install Spreadsheet::ParseExcel
ppm install Spreadsheet::WriteExcel4、将如下代码保存到d:\test.pl，更改里面的oracle的用户名和ip地址，以及端口号，以及sql语句
5、在命令行进入d盘下执行：perl test.pl
代码：
