How can I get the max value within a max value in mysql?

Question

I have a schema like the following

id (INT)
Cycle_Number (INT)
Cycle_Day (INT)
Date (date)

...other columns irrelevant to the question...

How can I get the row that has the max Cycle_Day within the max Cycle_Number

For example, say I have the following data

 ID Cycle_Number Cycle_Day Date 1 1 1 2011-12-01 2 1 2 2011-12-02 3 2 1 2011-12-03 4 2 2 2011-12-04 5 2 3 2011-12-05 6 2 4 2011-12-06 7 3 1 2011-12-07 8 3 2 2011-12-08 9 3 3 2011-12-09 

The query would return row 9. (It has the highest Cycle_Day within the highest Cycle_Number)

Thanks

Answer 1

this one is compatible MySql 5.5 with no joint tables

SELECT id
FROM cycles
ORDER BY Cycle_Number DESC , Cycle_Day DESC
LIMIT 0 , 1

This SQL query should provide the max value you want.

SELECT ID, Cycle_Number, Cycle_Day, Date
FROM  yourTable AS t
CROSS JOIN (
  SELECT MAX(Cycle_Number) AS Cycle_Number FROM yourTable
) AS sq USING (Cycle_Number)
ORDER BY Cycle_Day DESC LIMIT 1
