Six steps of JDBC linking Mysql database

Steps to link jdbc to mysql database

1. Load the driver

		//指定驱动方式
		Class.forName("com.mysql.jdbc.Driver");

2. Establish link url username password

		String url="jdbc:mysql://127.0.0.1:3306/test1";
		String usename="root";
		String password="root";
		Connection con=DriverManager.getConnection(url,usename,password);

3. Create a Statement object, (or a platform for executing SQL statements)

		Statement sta=con.createStatement();

4. Execute sql statement

	
		int row =sta.executeUpdate("insert into userinfo values('bob','789','[email protected]','22','man')");
		//ResultSet rs=sta.executeQuery("select Id from usermessage");

5. The fifth step is to process the execution result

		ResultSet rs=sta.executeQuery("Select*from userinfo");
		while(rs.next()) {
    
    
			String name=rs.getString("username");
			String sex=rs.getString("sex");
			//打印输出
			System.out.println("姓名："+name+"性别："+sex);
		}

6. Close link

		sta.close();
		con.close()；

• The operation of jdbc linking oracle database is only different in loading the driver and establishing the link
