Question

Hi am quite new to php yii i have following query

how can i write in to php yii using CDBcriteria

Answer 1

you can't get 'devices' (d.*) FROM 'customer_service_provider' with $criteria and CActiveDataProvider.

Because CActiveDataProvider need a model to convert the query result in a list of objects of that model, but in this case you would have to pass the model 'customer_service_provider' class.

sorry for my english..
