java使用jdbc操作数据库示例分享

这篇文章主要介绍了java使用jdbc操作数据库示例,需要的朋友可以参考下

package dao;

import java.sql.*;

public class BaseDao {

 //oracle

// private  static final String Dirver="oracle.jdbc.driver.OracleDriver";

// private  static final String URL="jdbc:oracle:thin:@localhost:1521:XE";

// private  static final String name="admin";

// private  static final String pass="123";

 //sqlserver

// private static final String Dirver="com.microsoft.sqlserver.jdbc.sqlServerDriver";

// private static final String URL="jdbc:sqlserver://localhost:1433;DatabaseName=TBLdb";

// private static final String name="sa";

// private static final String pass="sa";

 //MysqL

 private static final String Dirver="com.MysqL.jdbc.Driver";

 private static final String URL="jdbc:MysqL://127.0.0.1:3306/school";

 private static final String name="root";

 private static final String pass="123456";

 public  Connection getCconnection()

 {

  Connection cull;

  try {

   Class.forName(Dirver);

   conn=DriverManager.getConnection(URL,name,pass);

  } catch (Exception e) {

   e.printstacktrace();

  }

  return conn;

 }

 public void closAll(Connection conn,PreparedStatement ps,ResultSet rs)

 {

  try {

   if(null!=rs)

    rs.close();

   if(null!=ps)

    ps.close();

   if(null!=conn)

    conn.close();

  } catch (Exception e) {

   e.printstacktrace();

  }

 }

 public int executeUpdate(String sql,String parms[])

 {

  Connection cull;

  PreparedStatement ps=null;

  int result=-1;

  try {

   conn=getCconnection();

   ps=conn.prepareStatement(sql);

   if(null!=parms){

    for(int i=0;i     ps.setString(i+1,parms[i]);

    }

   }

   result=ps.executeUpdate();

   execute();

  } catch (Exception e) {

   System.out.println(e.getMessage());

  }finally{

   closAll(conn, ps, null);

  }

  return result;

 }

  public static void main(String[] args)throws Exception

 {

  BaseDao b=new BaseDao();

  Connection con=b.getCconnection();

  System.out.println(con.isClosed());

 }
