also have you tried running these lines directly in a cmdline sql client?
is the status column variable width? if not then the value may be 'Active ' (number of padded spaces dependent on length of the field) instead of 'Active'.
LightBulbMoment (tm): 5 seconds of searching on the MYSQL site tells me STATUS is a keyword. try either renaming your field or using backticks to escape the name e.g.:
$query = 'UPDATE EMPLOYEE SET `STATUS`=\'Inactive\' where `STATUS` IS NULL';
I'm willing to bet you haven't bother to:
a. RT(F)M. b. check the errors returned.

My "status" column in my Employee table should have two values "Active" and "Inactive". Right now all the active employees have the value "Active" and the rest have a NULL value.
Why is it that the following commands do nothing?
UPDATE EMPLOYEE SET STATUS='Inactive' where STATUS != 'Active';
UPDATE EMPLOYEE SET STATUS='Inactive' where STATUS <> 'Active';
these should work - expect for the STATUS keyword issue.
UPDATE EMPLOYEE SET STATUS='Inactive' where STATUS IS NULL';
this one has a typo (extra ' at the end)
UPDATE EMPLOYEE SET STATUS='Inactive' where STATUS = '';
UPDATE EMPLOYEE SET STATUS='Inactive' where STATUS = NULL;
these 2 shouldn't work at all.
