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 />
