I have a report with a parameter form containing a parameter called "person_name". As of now, it is a dropdown list which is built using a select query over my "people" table and displays all the people in the table. I need to add a checkbox on the parameter page which says "Show only current people" and when this checkbox is checked, the "person_name" dropdown list should be limited to only current people. I don't know how to add a checkbox to the parameter form, and how to implement this conditional if-then-else on the dropdown list.

My current query for the dropdown list is:
SELECT 1 co11,' ALL - ALL' col2
FROM dual
UNION
SELECT person_seq_num col1, last_name||','||first_name col2
FROM people
ORDER BY 2 asc


When the checkbox is checked, my query needs to be:
SELECT 1 co11,' ALL - ALL' col2
FROM dual
UNION
SELECT person_seq_num col1, last_name||','||first_name col2
FROM people
WHERE person_current_flag='Y'
ORDER BY 2 asc


Can anyone help with this problem? Thanks in advance.

Not possible (as far as I can tell).

Allegedly possible with some help of Java code; however, I have never seen actual proof as a person who said he did it never replied in order to share the solution.

That's what i thought..i've never seen such an implementation before. I just wanted to be sure.

Any suggestions for a work around? Achieving this functionality would be good. I can't think of an alternative except creating a separate dropdown list!

I've already mentioned a possible workaround in a reply to the "Not possible" linked topic (create your own parameter form using Forms Builder).
