Answer 1

Try this

$criteria = new CDbCriteria();
// instead of t specify the table name as such. For eg if the table involved is Job then

$criteria->select = 'jobs.title,  location.title,  jobs.key_skills, jobs.description, jobs.no_vacancy, jobs.experience, jobs.company_name, jobs.salary';
$criteria->join = 'INNER JOIN location ON jobs.location_id = location.id';

Answer 2

I am not giving you the exact solution but I have already faced this type of problem and solved it by using

$criteria->addInCondition

in place of

$criteria->addCondition

Please try this once. It may solve your problem. or

public function actionadvance_search_result()
{
$title=$_GET['title'];
$experience=$_GET['experience'];
$location=$_GET['location'];
$category=$_GET['category'];
$salary_min=$_GET['salary_min'];
$salary_max=$_GET['salary_max'];
$criteria = new CDbCriteria();
$criteria->select = 't.title,  location.title,  t.key_skills, t.description, t.no_vacancy, t.experience, t.company_name, t.salary';
$criteria->join = 'INNER JOIN location ON t.location_id = location.id';
if($experience!="")
{
  $criteria->addCondition("(location.title like '%$title%' or  location.key_skills like '%$title%') and (jobs.experience like '%$experience%')");    
}
if($location!="")
{
   $criteria->addCondition("jobs.location_id like '%$location%'");
}
if($category!="")
{
   $criteria->addCondition("jobs.category_id like '%$category%'");
}
if($salary_min!="" && $salary_max!="")
    {
        $criteria->addCondition("jobs.salary >= '$salary_min' and jobs.salary <= '$salary_max'");
    }
$count=Job::model()->count($criteria);
$pages=new CPagination($count);
$pages->pageSize=2;
$pages->applyLimit($criteria);
$model=Job::model()->findAll($criteria);
$number_rec=count($model);

Happy Coding.
