结合Mysql和kettle邮件发送日常报表

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

SELECT city AS 城市,DATE_FORMAT(order_date,"%x%v") AS 年周,

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

结束
