MySQL manual describes values of the YEAR(2) field type as follows: values 00 - 69 mean 2000 - 2069 years and values 70 - 99 mean 1970 - 1999 years. MIN/MAX and comparison functions was comparing them as int values thus producing wrong result. Now the Arg_comparator class is extended with compare_year function which performs correct comparison of the YEAR type. The Item_sum_hybrid class now uses Item_cache and Arg_comparator objects to correctly calculate its value. To allow Arg_comparator to use func_name() function for Item_func and Item_sum objects the func_name declaration is moved to the Item_result_field class. A helper function is_owner_equal_func is added to the Arg_comparator class. It checks whether the Arg_comparator object owner is the <=> function or not. A helper function setup is added to the Item_sum_hybrid class. It sets up cache item and comparator. mysql-test/r/func_group.result: Added a test case for the bug#43668. mysql-test/t/func_group.test: Added a test case for the bug#43668. sql/item.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Now Item_cache_int returns the type of cached item. sql/item.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) To allow Arg_comparator to use func_name() function for Item_func and Item_sum objects the func_name declaration is moved to the Item_result_field class. sql/item_cmpfunc.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The Arg_comparator class is extended with compare_year function which performs correct comparison of the YEAR type. sql/item_cmpfunc.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The year_as_datetime variable is added to the Arg_comparator class. It's set to TRUE when YEAR value should be converted to the YYYY-00-00 00:00:00 format for correct YEAR-DATETIME comparison. sql/item_geofunc.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Item_func_spatial_rel::val_int chenged to use Arg_comparator's string buffers. sql/item_subselect.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Added an implementation of the virtual func_name function. sql/item_sum.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The Item_sum_hybrid class now uses Item_cache and Arg_comparator objects to correctly calculate its value. A helper function setup is added to the Item_sum_hybrid class. It sets up cache item and comparator. sql/item_sum.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The Item_sum_hybrid class now uses Item_cache and Arg_comparator objects to correctly calculate its value. Added an implementation of the virtual func_name function. |
