title: Oracle OCI-Lob and ActiveRecord in Yii2
body: <p>I have a CLOB column in my oracle db, but when I fetch it via ActiveRecord findOne,
  I get this error:</p>
  
  <p>Object of class OCI-Lob could not be converted to string</p>
  
  <p>I know there is a workaround using dao, but my question is:
  Is there a way to work with ActiveRecord and CLOB?</p>
  
  <p>Thank you</p>
