The problem is that Item_direct_view_ref which is inherited from Item_ident updates orig_table_name and table_name with the same values. The fix is introduction of new constructor into Item_ident and up which updates orig_table_name and table_name separately. mysql-test/r/metadata.result: test case mysql-test/t/metadata.test: test case sql/item.cc: new constructor which updates orig_table_name and table_name separately. sql/item.h: new constructor which updates orig_table_name and table_name separately. sql/table.cc: used new constructor
