最近实践周,再次用到了这个Apache的开源工具包就在次对着个方面进行了复习
1.JDBC的基本 操作姿势
2.JDBC的步骤是
1.添加驱动包
Class.forName("oracle.jdbc.driver.OracleDriver");
2.加载驱动包
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@fwwb-439:1521:home", "scott", "tiger");
3.获取数据库连接
ResultSet rs = conn.prepareStatement("slect * from emp");
4.获取preparedStatement对象
5.执行sql
ResultSet rs = ps.executeQuery();
6.获取数据
while(rs.next()){
String no = rs.getString(1);
String name = rs.getString(2);
String job = rs.getString(3);
double sal = rs.getDouble(6);
System.out.println(no+","+name+","+job+","+sal);
}
7、释放资源
rs.close();
ps.close();
conn.close();
