Join ?

hi

i have 2 table that relation together: tl_user(sid is Primary key) $ tl_tel(id is Primary key , sid is Foreign key)

i want to Join 2table, but i can’t.

thank you

Inside the model find this function and write down their relationships:

inside both the models

let the below be inside student model:


public function relations()

	{

		return array(

                    

                   'studentTel'=>array(self::HAS_MANY, 'Tel','sid'),

                   //'name of relationship'=>(self::type of relationship,'the table name that u r trying to join with','foreign key attribute') 

		

                   );

		

		

	}

And

let the below be inside The foreign key table model:


public function relations()

	{

		

		return array(

                    

                   'studentTel'=>array(self::BELONGS_TO, 'Student','sid'),

//'name of relationship'=>(self::type of relationship,'the table name that u r trying to join with','foreign key attribute')

                );

		

	}

This is one way of defining relationship…

thank you , but want that join in Query! After you have defined relationships

suppose u have two tables: Student and Tel.


$model=Student::model()->findAll(array(

                'condition' => "stuid=1",

                'with'=>array('studentTel'), // the name of relationship that u write in model.

                'select'=> array("*"),

                ));

if i am making relationship between two tables, then i usually use same relationship name…

By default "t." points to the first table and if u want to use the second table also then write "t2."

Ex: ‘condition’ => “t.stuid=1 AND t2.name=‘ABC’”,

suppose u want to display student name and Tel name in ur view. for displaying student u will use


foreach($model As $mod)

{

  echo $mod['stuname'];// since this field is directly coming from student table, no need to use relationship here

  echo $mod->studentTel['telname']; // since this field is in another table, so u use relationship to display it.

}

thank you very very much.
