assertion .\filesort.cc, line 797 A query with the "ORDER BY @@some_system_variable" clause, where @@some_system_variable is NULL, causes assertion failure in the filesort procedures. The reason of the failure is in the value of Item_func_get_system_var::maybe_null: it was unconditionally set to false even if the value of a variable was NULL.
