yii ,sql, 增删改查
[color=#0000FF]1.$sql= "insert into tbl_user(`id`,`username`,`password`)values(null,'alu','123');
2.$sql= "select * from tbl_user where id=1;
3.$sql= "update tbl_user set password="123456" where id=6";
4.$sql= "delete from tbl_user where id=6;";
//设置字符编码
mysql_query("set names utf8");
$result=mysql_query($sql) or die('sql语句错误，系统给的提示是:'.mysql_error());

5.$num = mysql_num_rows($result)以及$num=mysql_fetch_array($result);
以上语句在yii框架里面应该怎样写？[/color]
------解决方案--------------------
好象回过你一个贴子，再回一次吧：

<br />utf8编码写到配置文件main.php中：<br />'db'=>array(<br />'connectionString' => 'mysql:host=localhost;dbname=test',<br />'emulatePrepare' => true,<br />'username' => 'root',<br />'password' => '123',<br />'charset' => 'utf8',  //此处设定编码<br />'tablePrefix' => 'tbl_',<br />),<br />控制器中：<br />  $conn=Yii::app()->db;<br />  $command=$conn->createCommand();<br />直接写语句：<br />  $command->text='select * from {{user}} where id=1';<br />  $dataReader=$command->query();<br />读取数据：<br />  foreach($dataReader as $row)<br />     { echo $row['name']; }<br /><br />  INSERT, UPDATE 和 DELETE 操作语句写法和上面类似，不过用execute：<br />  $rowCount=$command->execute();返回影响行数； <br />

Copy after login

------解决方案--------------------
其实简单的CRUD操作，用ActiveRecord不是更方便吗？
$model = User::model()->findByPk(1);

$model->password = 'new password';

$model->save();
------解决方案--------------------
用yii内置的方法
