during row insert DB_FOREIGN_DUPLICATE_KEY in row_ins_duplicate_error_in_clust was motivated by handling the cascade changes during versioned operations. It was found though, that certain row_update_for_mysql calls could return DB_FOREIGN_DUPLICATE_KEY, even if there's no foreign relations. Change DB_FOREIGN_DUPLICATE_KEY to DB_DUPLICATE_KEY in row_ins_duplicate_error_in_clust. It will be later converted to DB_FOREIGN_DUPLICATE_KEY in row_ins_check_foreign_constraint if needed. Additionally, ha_delete_row should return neither. Ensure it by an assertion. |
