jdbc操作mysql数据库实例

本文实例讲述了jdbc操作mysql数据库的方法。分享给大家供大家参考。具体如下：

import java.sql.*;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
class conn{
String url="jdbc:mysql://127.0.0.1/nariData";
final String user = "nari";
final String pass = "nariacc";
Connection conn = null;
Statement st = null;
ResultSet rs = null;
conn(){
 try{
  Class.forName("com.mysql.jdbc.Driver");
 }catch(Exception e){
  e.printStackTrace();
 }
 try{
  System.out.println("in DBManager");
  conn = DriverManager.getConnection(url, user, pass);
  String sql = "create table test (id int, uid int)";
  st = conn.createStatement();
  st.execute(sql);
 }catch(Exception e){
  e.printStackTrace();
 }
}
void insert(){
 try{
  for(int i=0;i<10;i++){
   String sql = "insert into test values("+i+","+i+")";
   st.execute(sql);
  }
 }catch(Exception e){
  e.printStackTrace();
 }
}
void query(){
 try{
  String sql = "select * from test ";
  rs = st.executeQuery(sql);
  while(rs.next()){
   System.out.print("res1: "+rs.getInt(1)+" res2: "+rs.getInt(2)+"\n");
  }
 }catch(Exception e){
  e.printStackTrace();
 }
}
void close(){
 try{
  rs.close();
  st.close();
  conn.close();
 }catch(Exception e){
  e.printStackTrace();
 }
}
}
public class mysqltest {
public static void main(String[] args) {
 // TODO Auto-generated method stub
 conn a1 = new conn();
 a1.insert();
 a1.query();
 a1.close();
}
}

希望本文所述对大家的JSP程序设计有所帮助。
