Alexander Barkov	cc9cfecab7	MDEV-8865 Wrong field type or metadata for COALESCE(signed_int_column, unsigned_int_column) ... Item_func_hybrid_field_type did not return correct field_type(), cmp_type() and result_type() in some cases, because cached_result_type and cached_field_type were set in independent pieces of the code and did not properly match to each other. Fix: - Removing Item_func_hybrid_result_type - Deriving Item_func_hybrid_field_type directly from Item_func - Introducing a new class Type_handler which guarantees that field_type(), cmp_type() and result_type() are always properly synchronized and using the new class in Item_func_hybrid_field_type.	2015-09-30 12:37:34 +04:00
