Hi
i have a parameter in my report set to list of values
select dp_name from dept;
dp_name is - IT,Bussiness.........etc
when the user select a department the specific records are displayed.
Now i want to add 'ALL' to my parameter LOV so that if the user selects 'ALL' ,all the departments will be displayed.
I tried :
LOV list of values as :
select null from dual
union
select dp_name from dept;
then my query was:
SELECT .....FROM ...where
INV_DEPT.DP_NAME = NVL(:p,INV_DEPT.DP_NAME)
it works okee....
but i dont want 'null'...i want all to be written in my LOV and then make changes to the query....
Any ideas ?
what changes will be made to the query.
Thanks.
Charu.

Obviously, as it won't be NULL again, NVL function won't help. Perhaps you should consider using the DECODE function instead, something like
where INV_DEPT.DP_NAME = DECODE(:parameter_value, 'All', inv_dept.dp_name,
:parameter_value
)
As of smilies in your messages: before pressing the "Submit Reply" button, I'd suggest you to "Spell-check Message" - it will both preview it and show all errors you have made. Doing so, you'd see a smiley and be able to disable it (see the screenshot), as well as fix spelling errors you have made. It will both make your messages much more readable.
