How to count the number of time series rows for multiple devices in Apache IoTDB?

How do I count the number of rows for the data stored in Apache IoTDB? I want to count the number of rows of multiple devices instead of just counting the number of rows of a certain device. Anyone know how to write the query statement in IoTDB to do this?
