Subject: BUG#25106: A USING clause in combination with a VIEW results in
 column            aliases ignored When a column reference to a column in JOIN
 USING is resolved and a new Item is created for this column the user defined
 name was lost. This fix preserves the alias by setting the name of the new
 Item to the original alias.

sql/sql_base.cc:
  BUG#25106: A USING clause in combination with a VIEW results in column
             aliases ignored

     allocated Item.
