Query the average, maximum, and minimum values for table `d10` in 1 second intervals:
```sql
select avg(current), max(voltage), min(phase) from test.d10 interval(10s);
select first(ts), avg(current), max(voltage), min(phase) from test.d10 interval(1s);
```
In the query above you are selecting the first timestamp (ts) in the interval, another way of selecting this would be _wstart which will give the start of the time window. For more information about windowed queries, see [Time-Series Extensions](../../taos-sql/distinguished/).
