This one could work:
WITH t AS (SELECT ROWNUM rn,
                  ' abcdefghijklmnopqrstuvwxyz' char_table
             FROM all_objects)
SELECT 1000 + ROWNUM - 1 empid,
       'king ' || char_counter,
       100 + (ROWNUM - 1) * 100 sal
  FROM (SELECT char_counter
          FROM (SELECT SUBSTR(t1.char_table, t1.rn, 1) || SUBSTR(t2.char_table, t2.rn, 1) char_counter
                  FROM t t1,
                       t t2
                 WHERE t1.rn <= 27
                   AND t2.rn <= 27
                   AND t2.rn >  t1.rn
         ORDER BY char_counter
WHERE ROWNUM <= 100
; C.
