How to select the bigger date between 2 columns? – Mysql

I have a table ‘processes’ with the following columns :

• id
• date_creation
• date_lastrun

For example I have the following entries:

id;date_creation;date_lastrun
1;2022-01-01 00:00:00;2022-02-01 00:00:00
2;2022-03-01 00:00:00;NULL

I want to select the element with the bigger date in MySQL
I can do

SELECT id, MAX(IFNULL(date_lastrun, date_creation)) as lastdate 
FROM processes

It’s OK it works but now I want to get the element with the bigger date compared to a specific date time.
I tried :

SELECT id, MAX(IFNULL(date_lastrun, date_creation)) as lastdate 
FROM processes 
WHERE DATE(lastdate) > "2022-03-01"

but it returns *#1054 – Unknown column ‘lastdate’ in ‘where clause’

SELECT id, MAX(IFNULL(date_lastrun, date_creation)) as lastdate 
FROM processes 
WHERE DATE(MAX(IFNULL(date_lastrun, date_creation))) > "2022-03-01"

but it returns #1111 – Invalid use of group function

Do you have any idea how to accomplish that?

I hope to return the element with the bigger date compared to a specific date.
