-----------------------------------
Hi, [~XiangweiWei]
Nice to hear your opinion, but I have a different idea. I think the meaning of
the _path_ in iotdb should be consistent with each other,
For example, when we execute the following commands:
_select * from root.ln.sg.device_
I think the from statement ‘_root.ln.sg.device_’ is a prefix path, the output
results of those timeseries's prefix are _root.ln.sg.device. N_ot
_root.ln.sg.device1._ _root.ln.sg.device2. and so on._
So I prefer to think the path is a prefix path
> fix prefix bug on show storage group and show devices

> When we use 'show storage group',we can see that root.ln is a storage group
> !image-2020-09-08-19-28-52-515.png!
> then use 'show storage group roo.ln.sgcc',
> !image-2020-09-08-19-30-30-852.png!
> The correct result should be empty
> Similarly, when the incoming path is a time series, using show devices prefix
> will return the corresponding device path
> We need to return the corresponding result only when the current prefix path
> is the prefix of the result
