陈哲涵 commented on IOTDB-5066:
----------------------------

这里的 show data regions 和 show regionid 本身是两个sql。。。前者里面的 SlotNum 
指的是每个region里面的槽个数,后者的 id 指的是根据这两个 id 来找对应的 region。比如 SeriesSlotNum 为 4,可能这 4 个的 
id 分别是 1933,1241,1432,1434 这样的

> 1. add query sql using timestamp。 `show Data RegionId of root.test.g_1 where 
> seriesSlotId=4468 and timestamp=1536796800012`。  timestamp can be any value, 
> we should calculate the timeslot of given timestamp 
>  
> 2. can show region of given deviceId.   `show Data RegionId of root.test.g_1 
> where seriesSlotId=4468`  => `show Data RegionId of root.test.g_1 where 
> deviceId=root.tesst.g_1`
>  
> 3. timeslotId =  timestamp % time_partition_interval. The query sql used 
> timestamp as timeslotId now.
>  
> 4. The show slot id should be in order.
>  
> 5. modify user doc
