怎这样的数据怎样插入oracle一张表中

Question

数据库表
create tables A(
shidm varchar2(50),//市代码
shinm varchar2(50), //市名称
zhendm shidm varchar2(50),
zhennm shidm varchar2(50)
)数据
1234  虚拟市1    null  （A,B,C,D,E,F,G,H,I）//这是excel表单中的一列数据；
插入数据库规则
  插入数据库表A    shidm》》1234，shinm》》虚拟市1， zhendm》》这个根据后面有多少列来插入，数据的编码规则是，存在一列1234+01（效果123401），依次递增。 zhennm》》每次获取一个，加上前面三个字段，形成一行（
下面是导入到数据库的两行
1234  虚拟市1   123401  A；
1234  虚拟市1    123402  B）。其他的依次生成请问我应该怎样将数据有excel直接插入到oracle。

Answer 1

--创建一个中间表，把execle数据先导进中间表，
create table temp(
   shidm varchar2(50),
   shinm varchar2(50),
   zhennm varchar2(500)
)insert into temp value ('1234','虚拟市1','A,B,C,D,E,F,G,H,I');
insert into temp value ('5678','虚拟市2','J,K,L,M');
commit;select * from temp;select t1.shidm,
       t1.shinm,
       t1.shidm || lpad(r, 2, '0') zhendm,
       substr(t1.zhennm, 2 * r - 1, 1) zhennm
  from temp t1,
       (select rownum r
          from dual
        connect by rownum <=
                   (select max(length(replace(zhennm, ','))) from temp)) t2
 where length(replace(t1.zhennm, ',')) >= r
 order by t1.shidm, t1.shinm, t2.r
 
 SHIDM                                              SHINM                                              ZHENDM                                                 ZHENNM

Answer 2

你好！谢谢你的回答。可能第一次发帖吧。我的需求不清吧。
我想要的结果是 
  shidm    shinm       zhendm        zhennm     
  1234     虚拟市1     123401          A
  1234     虚拟市1     123402          B
  1234     虚拟市1     123403          C
镇名称，有多少个，就在是代码（1234）后面自动添加一位。
可以的话请帮忙想想
