Answer 1

As Frank said, you likely want a join, and likely an outer join to replicate the select in the projection. Something like:
SELECT id,stat, section, USER_ID concerned_person
FROM table_all,
  left join table2
    on room_id = sectoion and
       sur_role = 'r001'
WHERE section IN (SELECT code
                  FROM t_area
                  WHERE dept= 'p002')An alternative, depending on where and how you are using the statement would be something like:
SQL> WITH t AS (
  2    select 1 id from dual union all
  3    select 2 id from dual),
  4  t1 as (
  5    select 1 id, 'One' descr from dual union all
  6    select 1, 'Un' from dual union all
  7    select 1, 'Une' from dual)
  8  SELECT t.id, CURSOR(SELECT t1.id, t1.descr from t1
  9                      WHERE t1.id = t.id)
10  FROM t;
                  ID CURSOR(SELECTT1.ID,T
                   1 CURSOR STATEMENT : 2
CURSOR STATEMENT : 2
                  ID DESCR
                   1 One
                   1 Un
                   1 Une
                   2 CURSOR STATEMENT : 2
CURSOR STATEMENT : 2
