In PL/SQL, you must always select INTO a variable. Also, a SQL%NOTFOUND statement is not relevent with a SELECT INTO. If a single row is not returned, either a NO_DATA_FOUND or a TOO_MANY_ROWS exception will be raised.
declare
v_empno emp.empno%type;
begin
select empno
into v_empno
from emp
where empno = 9999;
exception
when no_data_found then
dbms_output.put_line(...);
end; |
