Assume that we have a model with two columns, they are id and account_name

$datas = Account::model()->findAll();

echo CJSON::encode($datas);

[{"id":"1","account_name":"Tea"},{"id":"2","account_name":"Food"},{"id":"3","account_name":"Travel"},{"id":"4","account_name":"Pettycash"}]

$single->account_name = "New Tea";  // actual value is Tea

$single->save();
