今天工作的时候,用到了oracle数据库建表,发现navicat中对于oracle的支持没有那个主键自增的按钮,网上查了下,就此记录

建表：

CREATE TABLE "API_ATTENDANCE"

    ( "ID" NUMBER(10,0) NOT NULL ENABLE,

        "ATTENDANCE_DATE" DATE,

        "ATTENDANCE_TIME" DATE,

        "ATTENDANCE_URL" VARCHAR2(2000),

        "USER_ID" NUMBER(10,0),

        PRIMARY KEY ("ID")）；

建序列

CREATE SEQUENCE API_ATTENDANCE _sequence

MAXVALUE 9999999999999

MINVALUE 1

START WITH 1

INCREMENT BY 1

CACHE 20;

建触发器

create trigger API_ATTENDANCE _trig before

insert on API_ATTENDANCE for each row when (new.id is null)

begin

select API_ATTENDANCE _sequence .nextval into:new.id from dual;

 end;
