十一假期 参加婚礼 稍晚点发博

整体流程步骤是：

写SQL-导出到excel设定excel模板调整格式-设置kettle转换--设置kettle邮件作业--完成

第一、写SQL 保持最近12个周的数据

GROUP BY city ,DATE_FORMAT(order_date,"%x%v")

12周数据

第二步设定excel模板调整格式

主要设置上面sql语句要展示的表的表头 excel模板文件名 sheet表名

表头是执行kettle时候excel表输出时候的内容区域

excel模板文件名 是kettle调用此模板 按照模板设置输出表

sheet表名是kettle向excel表输出时候选择哪个sheet表（顾名思义 kettle是支持向多个sheet表输入数据的)

第三步 设置kettle转换 设置数据库连接 表输入步骤 excel表输出 步骤

将SQL代码输入  表输入（kettle-核心对象-输入-表输入）

设置表输出：核心对象-输出-microsoft excel表输出

###

绝对路径 相对路径 是在不同终端上使用kettle文件时可以正常使用  用相对路径比较好 主要用于在输出的文件名 和调用excel模板文件时候用到

使用相对路径快捷键：ctrl+alt+space 组合键

下面图 主要和上个图对比

原来的C:\Users\cxy\Desktop\ 绝对路径

转换为了 ${Internal.Transformation.Filename.Directory}相对路径 指向的是test文件所在的目录

调用excel模板同样道理

下一步 设置数据输出的起始位置

kettle 保存执行 这时候会在桌面（我设置的路径是桌面）生成test的excel文件

执行完毕 excel文件已生成

第四步 把生成文件设置成自动发送邮件

新建一个作业保存命名  调用上面的kettle转换文件 添加发送邮件控件  设置发件人信息 完成
