Execute a Select in the if conditon

Question

DECLARE
  vcount NUMBER;
BEGIN
  SELECT COUNT(*) INTO vcount FROM EMP WHERE EMPNO=7788;
  IF (vcount >=1) THEN
    DBMS_OUTPUT.PUT_LINE('emp exists');
  ELSE
    DBMS_OUTPUT.PUT_LINE('emp not exists');
  END IF;
END;The above code is working but the below one is not working. Can we execute a select stmt in the if conditon to check on the fly...?
DECLARE
BEGIN
  IF ((SELECT COUNT(*) FROM EMP WHERE EMPNO=7788) >=1)
  THEN
    DBMS_OUTPUT.PUT_LINE('emp exists');
  ELSE
    DBMS_OUTPUT.PUT_LINE('emp not exists');
  END IF;
END;Thanks

Just for your program,
you may even go with this instead of pl/sql.. (not sure about your original code though)
SELECT DECODE (COUNT (*), 0, 'Sorry no emp with that id', 'emp exists')
          chk_emp
  FROM emp
WHERE id = 1000;Cheers,
