Select List LOV will not accept query that seems to be valid

Question

Hi,
I modified an LOV query to add the number of results to the display_value return column. I have verified that the query works in SQL Workshop/SQL Commands, but when I paste it into the LOV it will not save changes. It says the LOV query is invalid....
To get it to apply I had to turn it into a Named LOV, and the page would load, but I get the error:
Error: ORA-06550: line 1, column 77: PL/SQL: ORA-01744: inappropriate INTO ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored performing List of Values query:
The query I am trying to perform is:
select STATUS.STATUS_NAME||' ('||
(select count(*)
from TICKET
where TICKET.USER_ID = (select USER_ID from LOGIN where upper(LOGIN.USER_NAME) = upper(:APP_USER))
and TICKET.STATUS_ID = STATUS.STATUS_ID)||')' display_value,
STATUS.STATUS_ID return_value
from STATUS
order by STATUS_ID
Here are the results when ran in SQL Commands:
DISPLAY_VALUE RETURN_VALUE
Defined (7) 0
Accepted (1) 1
In Process (0) 2
Completed (1) 3
Cancelled (0) 4
Thanks in advance for any help.

David,
Try the following and let me know what you get:
SELECT status.status_name || ' (' ||
   (SELECT COUNT(*)
    FROM ticket
    WHERE ticket.user_id IN
      (SELECT user_id
       FROM login
       WHERE UPPER(login.user_name) = UPPER(:app_user))
   AND ticket.status_id = status.status_id)
|| ')' display_value,
   status.status_id return_value
FROM status
ORDER BY status_idAlso, if you find you're using the user's id a lot, I would recommend creating an application level item called USER_ID (make it protected). Then I would add a little code in the post authentication process that sets the value of that item.
I'm not sure that there would really be much of a performance benefit, but you would have effectively SPODified (Single Point of Definition) the lookup allowing you to reference it where ever you need making your code look better and the maintenance easier.
Then the query would look like this:
SELECT status.status_name || ' (' ||
   (SELECT COUNT(*)
    FROM ticket
    WHERE ticket.user_id = :USER_ID)
   AND ticket.status_id = status.status_id)
|| ')' display_value,
   status.status_id return_value
FROM status
ORDER BY status_idRegards,
