Question

I have table with Timestamp, temperature and humidity. I want to have the average temperature in the periods where the humidity is above 80%. Something like

SELECT
MIN (DTM),
MAX (DTM),
AVG(TMP)
GROUP BY (WHERE HMD>80)

Is that possible?

Thank you

What I need is to define periods that start when the humidty rise above 80% and end when it comes bellow. Then I have to get the BEGIN timestamp the END timestamp and the average temperature

Answer 1

In the Group BY Clause you need to use CASE instead of WHERE :

SELECT MIN (DTM), MAX (DTM), AVG(TMP) GROUP BY (CASE WHEN HMD>80 THEN HMD END);
