      Fix for BUG#13410 - qualified reference to a view column in the HAVING clause cannot be resolved. · 58263844
      unknown authored
      The problem was then when a column reference was resolved to a view column, the new Item
      created for this column contained the name of the view, and not the view alias.
      
      
      mysql-test/r/view.result:
        Additional test for BUG#13410.
      mysql-test/t/view.test:
        Additional test for BUG#13410.
      sql/item.cc:
        Correctly cast 'cur_field' to Item_ident because if the original item is
        an Item_field, the cur_field is either an Item_field or an Item_ref.
        Thus we have to cast cur_field to a common super-class of both.
      sql/item.h:
        - real_item() may be called before Item_ref::ref is set
          (i.e. the Item_ref object was resolved).
        - To avoid a crash and to return some meaningful value
          in such cases we return 'this'.
      sql/sql_base.cc:
        - 'item' may be an Item_ref, so we test for the type of the actual
          referenced item.
        - Correctly cast 'cur_field' to Item_ident because if the original
          item is an Item_field, the cur_field is either an Item_field or an
          Item_ref. Thus we have to cast cur_field to a common super-class
          of both.
      sql/table.cc:
        - When creating a new Item for a reference to a view column, use the view alias,
          and not the real view name.
        - Removed old code
