A bug in ORACLE Report query??

Question

I need to modify my report by adding a description. I can run my query from SQL statement without a problem. However, when i put it in the report, strange result is happening.
The result for 1 record used to be 1 page only and now went up to the number of record in the child table.
Parent query:
SELECT event_id FROM events;
One of the child query is as follows:
SELECT event_id, decode(m_event , 0, ' ', 'X') e_major_ind
FROM event_responders
I need to make a modification by adding following to the query:
(select decode (major_event, 0, ' ', ': '||meaning )
from domain where domain = 'EVENTRESPONDERS_MAJOR_EVENT' and value = major_event)
So currently I have the following:
SELECT event_id, decode(m_event , 0, ' ', 'X') e_major_ind,
(select decode (m_event, 0, ' ', ': '||meaning )
from domain where domain = 'MAJOR_EVENT' and value = m_event) e_major_desc
FROM event_responders
As soon as I added that subquery, I got an unlinked icon in the query box in the Data Model page.
Any idea? Is this a known bug? or Am I missing something?
Thank you soo much for your help.

Answer 1

SELECT ER.EVENT_ID,
       DECODE(ER.M_EVENT, 0, ' ', 'X') E_MAJOR_IND,
       DECODE(ER.M_EVENT, 0, ' ', ': ' || DOM.MEANING) E_MAJOR_DESC
  FROM EVENT_RESPONDERS ER, DOMAIN DOM
WHERE DOM.DOMAIN = 'MAJOR_EVENT'
   AND DOM.VALUE = ER.M_EVENTIf you can't get it by joining to your reference code table, use a column formula to return the description.
Good luck.
