MYSQL查询以仅从当前日期选择列中的最大值

Question

I have the following table:

I want to run a query to select the maximum value from the 'MaxWind' column but only return the result from today's date.

You can probably see where I'm going here. I want the maximum windspeed for the current date. I would like to return what the value was and also the time it occurred.

Answer 1

This would work for "today":

select max(maxwind) from weather where stamp > '2015=10=16 0:00'

For each day, you could use CURDATE:

select max(maxwind) from weather where stamp >= CURDATE()
