How do i change (NULL) worth of a table? I've looked everywhere but did not find the correct answer.

Works, but updates rows:

UPDATE Club 
SET Place = 24
WHERE Place = NULL;

No longer working:

UPDATE Club 
SET Place = 24
WHERE Place IS NULL;

Something really worth trying

Update Club
Set Place = 24
where CLUBID in (Select CLUBID from Club where place is NULL)
