1. 隨機數包
select dbms_random.value
from dual;
2. 在[0..100]範圍內取隨機數
select trunc (dbms_random.value (0, 100))
from dual;
3. 大於字元『a』的10個字元隨機字串
select dbms_random.string ('a', 10)
from dual;
4. 單個小寫隨機字元
select chr (round (dbms_random.value (97, 122)))
from dual;
5. 在過去10天內取隨機日期
select to_date (trunc (dbms_random.value (to_number (to_char (sysdate - 10,
'j')
),to_number (to_char (sysdate, 'j')))),
'j')
from dual;
6. 在過去30分鐘內取隨機時間
select (sysdate - 1 / 24 / 60 * 30) + dbms_random.value (1, 1800) / 3600 / 24
from dual;
