SQL- Query that return only one record

Question

Hello,
is it possible to execute a pure SQL-Query which returns only one row although multiple rows are found.
It is no problem in PL/SQL, but I have no idea if the same is also possible in SQL.
thanks in advance
Michael

Answer 1

Why not? There are 4 records in this table, but only selected one.
SQL> with t
  2  as
  3  (
  4     select '#%$@#$@$@##$' Addr from dual
  5     union all
  6     select '18 Jalan Scott' from dual
  7     union all
  8     select '18 Lemana St' from dual
  9     union all
10     select '32-penstation' from dual
11     union all
12     select '99999999999' from dual
13  )
14  select addr
15    from t
16   where rownum =1
17  /
ADDR
#%$@#$@$@##$
