实验项目:使用kettle完成scott用户下的emp表数据抽取到hyl用户下emptest表 实验环境 操作系统:WIN7 数据库:Oracle11G R2 64 bit KETTLE版本:version 3.2.2 开始实验: 1. 查询scott用户下emp表的数据 2. hyl用户下创建实验表(emptest) 3. 查询hyl用户

实验项目:使用kettle完成scott用户下的emp表数据抽取到hyl用户下emptest表

 

实验环境

操作系统:WIN7

数据库:Oracle11G R2 64 bit

KETTLE版本:version 3.2.2

 

开始实验:

1. 查询scott用户下emp表的数据

\

2. hyl用户下创建实验表(emptest)

\

3. 查询hyl用户下实验表(emptest)数据

\

4. 配置kettle

点击“没有资源库”启动,之后添加数据库连接即可,如下图:

\

新建一个转换,如下图:

\

点击“表输入”,拖动到面板内,如下图:

\

同理,在输出项目中,选择“插入/更新”添加到面板内,如下图:

\

点击“表输入”图标,然后按住“SHIFT”,连接到“插入/更新”图标,如下图所示:

\

双击“表输入”图标,点击“新建”按钮,进入到如下配置界面,参考图下设置,完成数据库连接配置并进行测试,如下图所示:

\

完成“表输入”中数据库连接设置后,接下来按同样的方法对“插入/更新”图标下的数据库连接进行配置,参考配置如下:

\

完成,“表输入”和“插入/更新”的数据库连接配置后,双击“表输入”,进入如下界面,选择数据库连接为“scott”,也就是我们之前的数据源数据库,点击“获取SQL查询语句”,如下图所示:

\

选择我们要抽取的表,如下所示:

\

按提示点击“是”即可,如下图:

\

编写sql脚本,这里我们为使实验简单,源端和目标端的表结构是相同的,如下图所示:

\

双击“插入/更新”图标,对目标端进行配置,选择连接的目标端数据库hyl,点击&ldqu【本文来自鸿网互联 (http://www.68idc.cn)】o;浏览”获取目标表,如下图所示:

\

然后点击“获取字段”,你就可以看到源端和目标端的对应关系。点击“获取更新字段”你就可以看到我们要更新的字段都有哪些,如下图所示:

\

运行前,需要先保存kettle项目,进行保存,如下图:

\

万事俱备,只需运行了,如下图所示:

\

完成抽取后,会提示完成,如下图所示:

\

5. hyl用户验证实验表抽取数据情况

\

至此,我们完成了将scott的emp表数据抽取到hyl用户下的emptest表中,完成实验。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
