Gleb Shchepa	387a54fbbd	Bug #42778: delete order by null global variable causes ... 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.	2009-05-22 01:22:46 +05:00
