    Description

      Sometimes queries runs slow , but suddenly runs fast without "order by" clause
      or wrapping into a subselect like select * from (<select query>)

      Even every case must be fixed , it should be a possibility to force the behaviour
      of wrapping the query in a subselect, so application must not be changed,
      so something like

      columnstore_forced_subselect,

      so simply set

      set columnstore_forced_subselect = 1;

      can work as a workarround,

      Must be certainly dynamically and possible with global and session level.
