Could someone translate the following polish notation to its SQL counterpart: ['|', '&', ('is_company','=', True),('parent_id', '=', False),('company_name', '!=', False),('company_name', '!=', '')] My guess is : is_company = True OR parent_id = False AND company_name <> False AND company_name <> '' I could not get the concept of this notation no matter how hard I tried to understand it. Please help. UPDATE I was trying to extend the above notation to be: ((is_company = True AND parent_id = False) OR company_name <> False) AND company_name <> '' AND customer_type_id <> False I totally agree
