新浪sae的官方说明文档:http://apidoc.sinaapp.com/sae/SaeMysql.html

Class SaeMysql 具体实现:http://apidoc.sinaapp.com/__filesource/fsource_sae__saemysql.class.php.html

新浪官方文档已经给出了简单的示例:

<?php$mysql = new SaeMysql(); $sql = "SELECT * FROM `user` LIMIT 10";$data = $mysql->getData( $sql );$name = strip_tags( $_REQUEST[&#39;name&#39;] );$age = intval( $_REQUEST[&#39;age&#39;] );$sql = "INSERT  INTO `user` ( `name` , `age` , `regtime` ) VALUES ( &#39;"  . $mysql->escape( $name ) . "&#39; , &#39;" . intval( $age ) . "&#39; , NOW() ) ";$mysql->runSql( $sql );if( $mysql->errno() != 0 ){    die( "Error:" . $mysql->errmsg() );} $mysql->closeDb();?>
但是,我觉得还不够详细,尤其是对于初学者来说,或许这就是大牛的风格吧,给出的示例比较简短精辟。

我们一般对于数据库一般进行增、删、改、查的操作。

其中增加、删除、修改操作都是执行sql语句,然后根据错误代码看看是否正确执行了就可以了;

对于查询操作,一般分为两类:

查询得到一条记录,常用在登陆的时候查询用户名和密码的操作,SaeMysql类中对应方法getLine()返回的是一个一维数组;

查询得到多条记录,返回的结果是一个二维数组,需要使用两层foreach来进行输出,废话少说,上代码:

<?php	/*	 * Author:qianshou	 * Date  :2014/4/28	 * Comment:本来打算去上自习来着,计划又泡汤了	 */	$mysql	=	new SaeMysql();	//该类在初始化的过程中就完成了链接数据库的工作		//===============执行插入数据的操作==========================		$sql	=	"INSERT INTO `demo_table`(`id`,`name`,`password`) VALUES					(&#39;&#39;,&#39;qianshou&#39;,&#39;12345&#39;),					(&#39;&#39;,&#39;naruto&#39;,&#39;abcde&#39;),					(&#39;&#39;,&#39;kakaxi&#39;,&#39;asdfg&#39;)";		$mysql->runSql($sql);	//执行插入数据的操作		if($mysql->errno() != 0 )	{		die( "Error:" . $mysql->errmsg() );	}	else 	{		echo "Data inserted successfully!<br/>";	}		//=============执行取出数据的操作=============================		//取出一行数据		$sql	=	"SELECT * FROM `demo_table` WHERE `id`=&#39;1&#39;";		$row	=	$mysql->getLine($sql);		foreach ($row as $key=>$value)	{		echo $key."=>".$value."<br/>";	}		echo "<br/>next demo<br/><br/>";		//取出多行数据		$sql	=	"SELECT * FROM `demo_table`";		$result	=	$mysql->getData($sql);		foreach ($result as $row)	{		foreach ($row as $key=>$value)		{			echo $key."=>".$value."<br/>";		}		echo "===================<br/>";	}	$mysql->closeDb();?>

输出结果:

id=>1
name=>qianshou
password=>12345

next demo
id=>1
name=>qianshou
password=>12345
===================
id=>2
name=>naruto
password=>abcde
===================
id=>3
name=>kakaxi
password=>asdfg
===================
