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( $_REQUEST['name'] );$age = intval( $_REQUEST['age'] );$sql = "INSERT INTO `user` ( `name` , `age` , `regtime` ) VALUES ( '" . $mysql->escape( $name ) . "' , '" . intval( $age ) . "' , NOW() ) ";$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 ('','qianshou','12345'), ('','naruto','abcde'), ('','kakaxi','asdfg')"; $mysql->runSql($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`='1'"; $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
