oracle循环插入测试数据

ORACLE循环插入测试数据：

DECLARE v_num number(8):=2;v_index number(8):=1;v_name varchar2(255);v_code varchar2(15);begin   while(v_index<=v_num)  loop    v_code:='000000000'||TO_CHAR(v_index);    v_name:='name_'||SUBSTR(v_code,length(v_code)-7);        insert into t_person(PERSON_NAME)    VALUES(v_name);    COMMIT;    v_index:=v_index+1;    END LOOP while_loop;end;
