You can use MySQL's CASE Statement.

SELECT CASE situation
        WHEN 0 THEN 1
        ELSE 0
    END CASE
FROM users;

HQL also has the CASE expression. Check this link.

This depends highly on the DBMS.

You can use Oracle NVL or CASE as Marcelo suggests.

But I would go for a COALESCE SQL function.
