查询到的Yii CDbCriteria

Question

我需要使用CDbCriteria创建一个查询：

select t_devices.* 
from t_departmens, t_branches, t_cabinets, t_employees, t_devices 
where t_branches.id_organization = 1 
and t_departmens.id_branch = t_branches.id_branch 
and t_cabinets.id_department = t_departmens.id_department 
and t_employees.id_cabinet = t_cabinets.id_cabinet 
and t_devices.id_employee = t_employees.id_employee 

Answer 1

试试这个

$criteria = new CDbCriteria; 
$criteria->select('t_devices.*'); 
$criteria->from('t_departmens, t_branches, t_cabinets, t_employees, t_devices'); 
$criteria->condition('t_branches.id_organization = 1 
and t_departmens.id_branch = t_branches.id_branch 
and t_cabinets.id_department = t_departmens.id_department 
and t_employees.id_cabinet = t_cabinets.id_cabinet 
and t_devices.id_employee = t_employees.id_employee 
'); 

Answer 2

推荐的方法是使用的Active Record（AR）关系的模型文件。
