I have tables Ads
with column AdsId
, ClientId
and table Assigned
. Assigned has AdsId
as foreign key. I want to count the number of AdsId
in Assigned for given ClientId
. I have the following query which works but I am not sure if its the best way. How can I run the same query in yii? Hope I made my question clear.
SELECT A. * , (
SELECT COUNT( B.AdsId )
FROM Assigned AS B
WHERE B.AdsId = A.AdsId
AND A.ClientId =1
)
FROM Ads AS A
WHERE A.ClientId =1
LIMIT 0 , 30
First declare a relation in your model relations function
public function relations(){
return array(
...
'AdsIdCount'=> array(self::STAT,'Ads','AdsId'),
//'VarName'=>array('RelationType', 'ClassName', 'ForeignKey', ...additional options)
);
}
then in your in returned activeRecord results you can just call this count like this
$result = Assigned::model()->find($criteria);
$result->adsIdCount ; // do logic here
or
$results = Assigned::model()->findAll($criteria);
foreach ($results as $result){
$result->adsIdCount ; // do logic here
}
see STAT relation for more details on how this works http://www.yiiframework.com/doc/guide/1.1/en/database.arr#statistical-query
