Question

myeclipse怎么把数据添加到数据库啊？

Answer 1

首先打开Myeclipse，在工具栏上选择window->Show View->Other
选择Myeclipse database
双击DB Bowser
在控制台部分多出DB Bowser，右击空白处
选择new
在弹出的界面中
Driver template：MySQL Connector/]
Driver name:填写连接的名字(随意)
Connection url:jdbc:mysql://localhost:3306/数据库名
其中localhost表示本地数据库，如果是远程的则填写对方地址
数据库名表示你要连接的数据库的名称
User name:root
password:密码
然后添加jar包
这个时候你可以测试一下连接
单击Test Driver
如果连接成功则点击finsh
然后在控制台处
右击你的连接名
选择open connection
这样你就将Myeclipse与数据库连接了，连接后就可以向数据库里添加数据了

Answer 3

在myeclipse下面配置连接数据库，链接好之后，单击表，就可以创建一个表，然后选中表右键增加记录，录入数据后保存即可。

Answer 4

使用JDBC连接数据库或者使用myeclipse database explorer

Answer 5

可以直接在myeclipse中window-show view-db browser
