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]
[解决办法]
好象回过你一个贴子,再回一次吧:
utf8编码写到配置文件main.php中:
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=test',
'emulatePrepare' => true,
'username' => 'root',
'password' => '123',
'charset' => 'utf8', //此处设定编码
'tablePrefix' => 'tbl_',
),
控制器中:
$conn=Yii::app()->db;
$command=$conn->createCommand();
直接写语句:
$command->text='select * from {{user}} where id=1';
$dataReader=$command->query();
读取数据:
foreach($dataReader as $row)
{ echo $row['name']; }
INSERT, UPDATE 和 DELETE 操作语句写法和上面类似,不过用execute:
$rowCount=$command->execute();返回影响行数;
