fetching is very slow in yii using CDBcriteria - yii

Question

i have about 15000 rows in my table using cdbcrieria to fetch result , but it take too much time to load the result , can anyone please tell me the fastest way to fetch the result
i want the count of all fetched rows and method to fetch fastest result.Please help !
following is the code that i am currently using:
$criteria = new CDbCriteria;
// $Criteria->$criteria = 50;
$currentAction = Yii::app()->controller->action->id;
if ($currentAction == 'currentstock') {
$storeid = isset(Yii::app()->session['storeId']) ? Yii::app()->session['storeId'] : 0;
$criteria->condition .= ' storexparts.storeId="' . $storeid . '" AND ( partAppStatus="1" OR partAppStatus="15" OR partAppStatus="17" OR partAppStatus="22" ) ';
} else {
$userId = Yii::app()->user->id;
$storeid = isset(Yii::app()->session['storeId']) ? trim(Yii::app()->session['storeId']) : (isset($_REQUEST['storeId']) ? Yii::app()->session['storeId'] = trim($_REQUEST['storeId']) : '');
$criteria->condition = 'storexparts.storeId="' . $storeid . '"';
$criteria->condition .= ' AND userxfavparts.userId="' . $userId . '"';
$criteria->condition .= ' AND userxfavparts.storeId="' . $storeid . '"';
$criteria->condition .= ' AND (t.partAppStatus="1"';
$criteria->condition .= ' OR t.partAppStatus="15"';
$criteria->condition .= ' OR t.partAppStatus="17"';
$criteria->condition .= ' OR t.partAppStatus="22")';
// $criteria->order = 't.partCreateDate DESC';
}
$criteria->with = array('partUnit0', 'partCat0','fleetname', 'partType0', 'partSubCat0', 'storexparts', 'userxfavparts', 'partBrand0', 'partsalias','partPosXstore');
if (!empty($_GET['filterProperties'])) {
$string = implode("#", explode("\\", $_GET['filterProperties']));
$string = implode("#", explode("'", $string));
$code = stripslashes(trim($string));
$criteria->addCondition("partNumber LIKE CONCAT('%', :filterProperties , '%')

$criteria->params = array(':filterProperties' => $code);
}
$criteria->together = true;
if (isset($_REQUEST['Parts']) && !empty($_REQUEST['Parts'])) {
if (!empty($_REQUEST['Parts']['partAliasNumber'])) {
$partId = $_REQUEST['Parts']['partAliasNumber'];
$criteria->addCondition("partNumber LIKE CONCAT('%', :filterProperties , '%')

Very important: Your select must be optimized before any other thing. If you are using MySQL, you can check their official documentation to do it.
With your select properly optimized, I suggest you to create a database view with your RDMBS to avoid overload your query with fat ActiveRecords with a lot of data and metadata. DML for build definition, in MySQL, looks like:
CREATE OR REPLACE VIEW 'mydatabaseview' AS
(
SELECT
..... your select with all joins and minimal
..... WHERE conditions
)
Backing to the code, create a model with this database view. You can generate model with gii code generator. In generated model, into protected/models/Mydatabaseview.php make sure to define a method primaryKey():
class Mydatabaseview extends ActiveRecord
{
.....
// Define this method manually, because your database view
// don't have primary Key
public function primaryKey()
{
return 'field_from_database_view';
}
....
Finally, in same model in protected/models/Mydatabaseview.php, use your criteria as you want:
public function search()
{
$criteria = new CDbCriteria;
.......... all your conditions
}
If your issue continues, your probably need to use Yii Query Builder instead ActiveRecord. It implies to redesign your original concept.
