oracle with和insert結合使用

需求是這樣的，先在一個從句中根據sub_code查詢dis_code和reg_code,

再把這；兩個值作為insert value的一部分，差到rate表里，好了，這里提供一種常規做法，和一種用with實現的做法

常規做法：

insert into HW_RATE
    (ID,
     SUB_TYPE,
     DISTRICT_CODE,
     REGION_CODE,
     SUB_AREA_CODE,
     CREATE_DATE,
     CREATE_USER)
    select sys_guid(),
           2,
           o.district_code bu,
           o.region_code re,
           '60487',
           sysdate,
           'ww00068'
      from eis_user.org_office o
     where o.sub_area_code = '60487'
       and o.status = 1
       and o.year = extract(year from sysdate)
       and o.sub_type = 2

用with的用法：

insert into HW_RATE
    (ID,
     SUB_TYPE,
     DISTRICT_CODE,
     REGION_CODE,
     SUB_AREA_CODE,
     CREATE_DATE,
     CREATE_USER) 
     with areaInfo as
    (select o.district_code bu, o.region_code re
       from eis_user.org_office o
      where o.sub_area_code = '60487'
        and o.status = 1
        and o.year = extract(year from sysdate)
        and o.sub_type = 2)
    select sys_guid(),
           2,
           areaInfo.bu,//這里直接with 臨時表別名.子句查詢結果別名，即可
           areaInfo.re,
           '60487',
           sysdate,
           'ww00068'
      from areaInfo

唯一需要注意的就是，with語句后面直接只能跟select語句，稍微換下思路就可以吧insert和with結合使用了
