You could do...
SQL> ed
Wrote file afiedt.buf
  1  declare
  2    v_abc varchar2(20);
  3  begin
  4    SELECT
  5      CASE
  6        WHEN (select COUNT(*) from emp where empno = 1234) > 0 THEN
  7          (select ename from emp where empno = 1234)
  8        ELSE
  9          null
10      END
11    INTO v_abc
12    FROM dual;
13* end;
SQL> /
PL/SQL procedure successfully completed.But that's no better than doing a check first as a seperate SQL in the PL/SQL.
I would do this... (if I really didn't want the no_data_found exception)
