Solution 1

Did you even tried once?

Well, to start with, a logical way (date of death will not be filled and will be null until unless someone dies. Once dead, then only data is there!)

SQL

SELECT 
  id_Applicant, 
  name
FROM
  Applicant
WHERE
  date_of_death IS NOT NULL

:)

Now, if you need to use current date in your query based on some scenario, try by yourself. You almost have 90% of query with you.

All you need is one more condition to the WHERE clause. Give it a try.

Teaching a man to fish instead of giving him the fish. I like it. +5

Solution 2

this is the solution:

SQL

SELECT
  id_Applicant,
  name
FROM
  Applicant
WHERE
  date_of_death is NULL or date_of_death > 30-5-2012
