----------------------------
(flag) 标签已增加
这个问题时可以重现的。在kylin的sql执行窗口输入类似sql脚本也会使kylin奔溃。
> sql在解析>大值 and <小值的时候，kylin出现内存溢出。

> ) f
> group by f.plant_code,f.report_business_area,f.orderby
> order by orderby
> 以上的calendar_day条件，顺序输入反了，变成calendar_day>大值 and
> calendar_day<小值，出现了kylin内存溢出，并且崩溃。正常这种情况是没有数据输出才对。
