1、用jdbc_odbc桥连接oracle的代码如下：
public class Test2 {
public static void main(String[] args){
String driver="sun.jdbc.odbc.JdbcOdbcDriver";
String url="jdbc:odbc:test1";
String uname="scott";
String password="tiger";
Connection conn=null;
String sql="select * from emp";
try{
Class.forName(driver);
conn=DriverManager.getConnection(url, uname, password);
Statement sm= conn.createStatement();
ResultSet rs= sm.executeQuery(sql);
while(rs.next()){
String sname=rs.getString(2);
System.out.println("****名字="+sname);
}
}catch(Exception e){
e.printStackTrace();
}
}
***************************************************************************
2、用jdbc连接oracle 的代码如下：
public class Test3 {
public static void main(String[] args){
String driver="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@localhost:1521:orcl";
String uname="scott";
String password="tiger";
Connection conn=null;
String sql="select * from emp";
try{
Class.forName(driver);
conn=DriverManager.getConnection(url, uname,password);
PreparedStatement ptmt=conn.prepareStatement(sql);
ResultSet rs=ptmt.executeQuery();
while(rs.next()){
System.out.println("$$$姓名$$$="+rs.getString(2));
}
conn.close();
}catch(Exception e){
e.printStackTrace();
}
}
=========================================================
这里说一下PreparedStatement与Statement的区别？
理解oracle时最好用PreparedStatement因为PreparedStatement有预编译的作用
