Detailed Description

qx::QxSqlRelationLinked : hierarchy of relationships to build SQL query

Here is the structure, each real relation has a relation linked associated to build the hierarchy, like this :

(<root>, <relation_linked>)
   ("blog", blog_relation)
   ("blog", <relation_linked>)
      ("author", author_relation)
      ("author", <relation_linked>)
         ("list_blog", list_blog_relation)
         ("list_blog", <relation_linked>)
            (etc...)
      ("comment", comment_relation)
      ("comment", <relation_linked>)
         ("blog_id", blog_id_relation)
         ("blog_id", <relation_linked>)
            (etc...)
      ("category", category_relation)
      ("category", <relation_linked>)
         ("list_blog", list_blog_relation)
         ("list_blog", <relation_linked>)
            (etc...)
