使用jdbc，程式碼如下：



package com.example.mysql;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Util 
{
	final static String DRIVER_NAME = "com.mysql.jdbc.Driver";

	public static Connection openConnection(String url, String user,
			String password) 
	{
		Connection conn = null;
		try 
		{
			Class.forName(DRIVER_NAME);
			conn = DriverManager.getConnection(url, user, password);
		} 
		catch(ClassNotFoundException e) 
		{
			conn = null;
		} 
		catch(SQLException e) 
		{
			conn = null;
		}
		
		System.out.println(conn);
		return conn;
	}

	public static void query(Connection conn, String sql) 
	{
		if (conn == null) 
		{
			return;
		}
		
		Statement statement = null;
		ResultSet result = null;
		
		try 
		{
			statement = conn.createStatement();
			result = statement.executeQuery(sql);
			System.out.println(result);
			if (result != null && result.first()) 
			{
				int idColumnIndex = result.findColumn("id");
				int nameColumnIndex = result.findColumn("name");
				System.out.println("id\t\t" + "name");
				while (!result.isAfterLast()) 
				{
					System.out.print(result.getString(idColumnIndex) + "\t\t");
					System.out.println(result.getString(nameColumnIndex));
					result.next();
				}
			}
		} catch (SQLException e) 
		{
			e.printStackTrace();
		} 
		finally 
		{
			try 
			{
				if (result != null) 
				{
					result.close();
					result = null;
				}
				if (statement != null) 
				{
					statement.close();
					statement = null;
				}
			} 
			catch (SQLException sqle) 
			{
				sqle.printStackTrace();
			}
		}
	}

	public static boolean execSQL(Connection conn, String sql) 
	{
		boolean execResult = false;
		if (conn == null) 
		{
			return execResult;
		}
		
		Statement statement = null;
		
		try 
		{
			statement = conn.createStatement();
			if (statement != null) 
			{
				execResult = statement.execute(sql);
			}
		} 
		catch (SQLException e) 
		{
			execResult = false;
		}
		return execResult;
	}
}
