WangChao commented on IOTDB-622:
--------------------------------
> SELECT ...
> FROM ...
> GROUP BY time_interval | LEVEL n (,n2)* | time_interval, LEVEL n (,n2)*.
Good idea! Level number looks like the group name except that it could not be
set. After tag feature is completed, it will look like standard sql, and it's
more friendly to user.
> count all records of the whole database

> Now the count function only count the number of every timeseries, it's useful
> to count the total record of the specific path.
>
> like:
>
> *_select count(*) from root.ln._** should return the total number of the
> records in storage group root.ln, but now it returns the number of each
> timeseries which is in root.ln.
>
> Please leave your opinion.
