    Description

      SET @aaa = COLUMN_CREATE('sum', 18802.5);
      		 
      SELECT COLUMN_GET(@aaa, 'sum' AS DECIMAL);
      		 

      COLUMN_GET(@aaa, 'sum' as decimal)  
      ------------------------------------
      		 
      18803

      Expected see here 18802.5 because i not pointed here any restrictions for DECIMAL type

      So why by default DECIMAL works as INT? I think this is not expected and not correct.
