After adding an index the <VARBINARY> IN (SELECT <BINARY> ...) clause returned a wrong result: the VARBINARY value was illegally padded with zero bytes to the length of the BINARY column for the index search. (<VARBINARY>, ...) IN (SELECT <BINARY>, ... ) clauses are affected too. sql/item.cc: Fixed bug #28076. The Item_cache_str::save_in_field method has been overloaded to check cached values for an illegal padding before the saving into a field. sql/item.h: Fixed bug #28076. The Item_cache_str::is_varbinary flag has been added and the Item_cache_str::save_in_field method has been overloaded to prevent cached values from an illegal padding when saving in fields. The signature of the Item_cache::get_cache method has been changed to accept pointers to Item instead of Item_result values. sql/item_cmpfunc.cc: Fixed bug #28076. The Item_in_optimizer::fix_left method has been modified to to call Item_cache::get_cache in a new manner. sql/item_subselect.cc: Fixed bug #28076. The subselect_indexsubquery_engine::exec method has been modified to take into account field conversion errors (copy&paste from subselect_uniquesubquery_engine::exec). sql/sp_rcontext.cc: Fixed bug #28076. The sp_rcontext::create_case_expr_holder method has been modified to call Item_cache::get_cache in a new manner. sql/sp_rcontext.h: Fixed bug #28076. The sp_rcontext::create_case_expr_holder method signature has been modified to pass Item pointers to the Item_cache::get_cache method. sql/sql_class.cc: Fixed bug #28076. The select_max_min_finder_subselect::send_data method has been modified to call Item_cache::get_cache in a new manner. mysql-test/t/subselect.test: Added test case for bug #28076. mysql-test/r/subselect.result: Added test case for bug #28076. |
