SELECT m1
FROM
  (SELECT rownum m1 FROM dual d CONNECT BY LEVEL <1000
  )
WHERE NOT EXISTS
  (SELECT x
  FROM
    (SELECT ROWNUM x FROM DUAL CONNECT BY LEVEL <= (sqrt(1000))
    )
  WHERE x       > 1
  AND x         < m1
  AND mod(m1,x) = 0
  )
AND m1 > 1;

What you were missing was to add the condition that x < m1. For numbers less than 33 , this would mean the number itself.
