PostgreSQL中一些默认值写法

一、当前时间加上某些天数

(Now() + '365 days'::interval)

二、使用序列

1，序列写法

-- Sequence: memberaccount_cardautono

-- DROP SEQUENCE memberaccount_cardautono;

CREATE SEQUENCE memberaccount_cardautono
  INCREMENT 1
  MINVALUE 1
  MAXVALUE 9223372036854775807
  START 1
  CACHE 1;
ALTER TABLE memberaccount_cardautono
  OWNER TO admin;

2，默认值写法

nextval('memberaccount_cardautono'::regclass)
