1. 恢复MySQL数据库
(1)打开Navicat通过enron-mysqldum_v5.sql文件创建enron数据库
或者使用命令行恢复数据库,注意此处我将sql文件放置在桌面
(2)打开Navicat查看数据库,并新建查询:
SELECT DATE(date) AS dataset, COUNT(mid) AS numMSG
FROM message
GROUP BY date
ORDER BY date
2.打开kettle创建新的转换任务
(1)新建DB连接,设置好后点击测试。
(2)核心对象中找到表输入并配置
SELECT date(date) as datesent, count(mid) as numMsg
from message
where year(date) between 1998 and 2002
group by datesent
order by datesent
(3)配置excel输出
(4)运行转换
