I have a query please. If anyone could help me out. 
I have two models i.e. Model A and Model B. I have created a view using Left Join Query. Fetch the required fields from model A as well as model B. I have one binary field in Model A. I am unable to fetch that field. when I use it in a query, it gives an error that field does not exists in Model A. Moreover, that field is not showing in the database as it is in attachments and gets saved in ir_attachment model. 

Any suggestion how to fetch binary field in a join query please?
