Yii framework, adding and deleting sections, SQL

Yii frame, delete and change, SQL
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;";
Set character encoding
mysql_query ("Set names UTF8");
$result =mysql_query ($sql) or Die (' SQL statement error, the system gives the hint is: '. mysql_error ());

5. $num = Mysql_num_rows ($result) and $num=mysql_fetch_array ($result);
How should the above statement be written in the YII framework? [/color] [/color] SQL Yii Data deletion and modification Frame

------Solution--------------------
The UTF8 encoding is written to the configuration file main.php:
' DB ' =>array (
' connectionString ' = ' mysql:host=localhost;dbname=test ',
' Emulateprepare ' = true,
' Username ' = ' root ',
' Password ' = ' 123 ',
' CharSet ' = ' utf8 ',//Set code here
' Tableprefix ' = ' tbl_ ',
),
In the controller:
$conn =yii::app ()->db;
$command = $conn->createcommand ();
Direct Write statements:
$command->text= ' select * from {{user}} where id=1 ';
$dataReader = $command->query ();
Read data:
foreach ($dataReader as $row)
{echo $row [' name '];}

The INSERT, UPDATE, and DELETE operation statements are similar in wording to the above, but with execute:
$rowCount = $command->execute (); Returns the number of rows affected;

Or just build a table and use the GII to generate the appropriate crud
