Entering mulitple values for a single user parameter

Question

Hello,
Can anyone explain to me how to allow multiple values for a single parameter?
For example, say I want to allow the report to display a list of employees based on their employee id. I want to allow the user to enter mulitple
employee id's into a single field to get their report. SO the user would enter "241, 459, 832" to return the list of those 3 employees. I have the SQL set up below, but obviously I need to set up something different to break it out into 3 separate values. Any help would be greatly appreciated!
SELECT * FROM EMPLOYEE
WHERE EMPLOYEE_ID IN (:P_EMP_ID)

Hi,
Another way to do this is to use the lexical parameter, but then you have to create the parameter form in Forms. Your SQL would look like this for example:
select * from emp where empno is not null &empno
where &empno is a lexical parameter.
Then on your parameter form you would have a text field F_empid, say 200 character long, allowing the user to enter multiple values separated by a ",".
Then in the trigger that calls the report you would create a parameter list, and a variable that holds the values read from the form, this variable is where you define the value to be passed to the report's lexical parameter. For example:
declare
v_empid varchar2(200); (consistent with the length of the lexical parameter in the report).
begin
v_empid:='and empno in ('||F_empid||')';
then you pass v_empid to &empno in the call to the report.
This method works well. Good luck.
