Oracle数据库创建随机测试数据
(1)创建表test01
create table test01 ( col1 number, col2 number, col3 date, col4 varchar2(30), col5 varchar2(100) );
(2)创建自增序列
CREATE SEQUENCE seq01 START WITH 1 MAXVALUE 99999999 MINVALUE 0 CYCLE CACHE 10 ORDER;
(3)创建随机数据插入存储过程,其中col1列单调递增
create or replace procedure p_insert_test01 IS v_col1 NUMBER; BEGIN FOR i IN 1..10000 LOOP select seq01.nextval INTO v_col1 from dual; insert into test01(col1,col2,col3,col4,col5) values (v_col1, (select round(dbms_random.value(10000, 100000000)) from dual), sysdate, (select dbms_random.string('a', 25) from dual), (select dbms_random.string('a', 85) from dual)); END LOOP; commit; end p_insert_test01;
(4)制定job,没隔30s执行一次上面的存储过程
declare job1 number; begin sys.dbms_job.submit(job => job1, what => 'p_insert_test01;', next_date => sysdate, interval => 'sysdate + 30/(1440*60)'); --每隔30s向test01表插入10000笔随机数据 commit; end; /
