Question

The query in question is

SELECT MAX(Date) as max, MIN(Date) as min FROM 
table 
WHERE Id = 'id' 
ORDER BY Date DESC 
LIMIT 100

And what I want it to do is return the maximum and minimum date of the most recent 100 records. What it does is it displays the min and max from ALL the records.

Answer 1

You must first select the records you are interested in and then select max() and min() from those.

SELECT max(Date) AS max,
       min(Date) AS min
  FROM ( SELECT *
           FROM t
          WHERE Id = 'id'
       ORDER BY Date DESC
          LIMIT 100) x;
