hi, I have read that after select we use column-names but I have found a statement that was like this:

SELECT 'A' FROM T WHERE A = NULL;

would you lease help me? thanks (A is a column- name here?) my DBMS is MySQL

EDITED : the exact question is this that: Will the above statement produce a row (select all that apply)? Notice that ANSI_NULLS is OFF.

I want to know that the above statement will work? because some of you said that we should write IS NULL instead of =null
