CDbCriteria condition from another CDbCriteria

问题

I don't if that I want to do is possible or not, I have two models i want to get data from one model using a condition from another.

                    $criteria1=new CDbCriteria;
        $paramIds = $s['param_id'];
        $stress = model1::model()->find($criteria1);
        $mycondition= ($stress->stress_value);

        echo $mycondition ; // I get this value and I want to use it as  
                                        // condition for the next cdbcreteria

        $criteria2=new CDbCriteria;

                     // condition
        $criteria2->addcondition(array('pressure_value' >  $mycondition));

                      // I can't  perform this condition       

        $criteria2->order = "pressure_value desc";
        $pressure = model2::model()->find($criteria2);

Any idea ? my code is wrong or what I want to do is not possible in this way ?

Many thanks

thanks @Örs

your solution work for me with making the compare statement in cdbcreteria after the condition

$criteria2->params = array(':value' => $mycondition)
