mysql中自增主鍵：create table test（id primary keyAUTO_INCREMENT） AUTO_INCREMENT=值;

Oracle中沒有這種寫法，Oracle中自增主鍵，需要靠序列和觸發器實現

例：

drop table account_la;
create table account_la(
  customer_id integer,--主鍵
  customer_name varchar2(20) not null, --客戶名
  customer_id_card varchar2(20) not null, --客戶身份證號
  customer_sex char
 
(4) default'男' not null,--客戶性別
  customer_phone number(11) not null,--客戶手機號
  customer_password varchar2(128) not null,--密碼
  create_time timestamp default sysdate not null,--註冊時間，預設為系統當前時間
  bank_id integer not null,--銀行號
  customer_address varchar2(256) not null,--客戶地址
  customer_status integer default
 
 1 not null,--客戶賬戶狀態，0：不可用，1：可用
  account_balance varchar2(64) not null,--賬戶餘額
  constraint account_pk primary key(customer_id),
  constraint check_sex check(customer_sex in ('男','女')),
  constraint check_status check(customer_status in(0,1)),
  constraint unique_id_card unique(customer_id_card),
  constraint
 
 unique_phone unique(customer_phone)
);
drop sequence SEQ_account_autoid 
-- 建立account_la的序列，自增初始值為1，最大值為999999999999，每次加1
create sequence SEQ_account_autoid
minvalue 1
maxvalue 999999999999
start with 1
increment by 1
nocache;

drop trigger TRG_account_autoid;
-- 建立account_la的觸發器，每次插入值時查詢序列的nextVal（下一個序列值）
create trigger TRG_account_autoid before insert on account_la for each row when(new.customer_id is null)
begin 
  select SEQ_account_autoid.nextval into:new.customer_id from dual;
end;
