Im using this:
SELECT * WHERE id=MAX(id) FROM history;
But my query is empty. I have also tried this (This one works):
SELECT MAX(id) AS max_id FROM history;
But obviusly my query only contains the max_id key. What am I doing wrong with the first one?

You need to add another level of select
for the MAX
, like this:
SELECT * WHERE id=(SELECT MAX(id) from history) FROM history;
A better approach would be to order by id
in descending order, and limit the output to a single row:
SELECT * FROM history ORDER BY id DESC LIMIT 1
