表 assets_cards 的id 是表 LETTING_DETAILSES 的外鍵，表裏字段serial_number 的數據也以pre_serial_number字段存在 表LETTING_DETAILSES，id 與serial_number是一一對應的！
由於測試數據庫的表assets_cards與研發數據庫表assets_cards 中有部分資產數據的id、serial_number不一一對應，刪掉測試數據庫的不對應的數據，從研發數據庫導進這部分數據：
alter table LETTING_DETAILSES disable constraint FK51DEC93ACE7A0619; 停掉外鍵約束
1.開始導入數據ing：
insert into assets_cards s
(id,
accumulate_depreciation,
address,
amount,
assets_group_code,
assets_state,
brand,
car_number,
category_code,
company_code,

select hibernate_sequence.nextval,
t.accumulate_depreciation,
t.address,
t.amount,

t.handle_login,
t.exercise_on
from assets_cards@eam0315 t
where not exists (select serial_number
from assets_cards s
where t.serial_number = s.serial_number);
2.驗證是否導入重複的數據：
select serial_number from assets_cards t group by t.serial_number having count(t.serial_number)>1 ;
select id from assets_cards t group by t.id having count(t.id)>1 ;
3.確定無導入重複數據，更改表LETTING_DETAILSES的assets_card_id與表assets_cards 中的id對應
update (select r.assets_card_id,
r.pre_assets_card_id,
r.pre_serial_number,
a.id aid,
a.serial_number
from LETTING_DETAILSES r
left join assets_cards a
on r.pre_serial_number = a.serial_number
and r.assets_card_id <> a.id) aa
set aa.assets_card_id = aa.aid;
（有9萬條數據，用這種方法更新大概要 2秒左右）
4.重新啓用外鍵約束：
alter table LETTING_DETAILSES enable constraint FK51DEC93ACE7A0619;
