如下所示：

— 建表
CREATE TABLE if not exists public.user
(
id character varying(32) NOT NULL DEFAULT sys_guid(),
name character varying(100) NOT NULL,
gender character varying(50) NOT NULL,
age character varying(10) NOT NULL,
id_no character varying(50) NOT NULL,
created_date timestamp without time zone DEFAULT now(),
created_by character varying(100) DEFAULT ‘system’,
updated_date timestamp without time zone DEFAULT now(),
update_by character varying(100) DEFAULT ‘system’,
CONSTRAINT user_pkey PRIMARY KEY (id)
)with (oids = false);

— 注釋
COMMENT ON TABLE public.user IS ‘用戶表’;
COMMENT ON COLUMN public.user.id IS ‘主鍵’;
COMMENT ON COLUMN public.user.name IS ‘姓名’;
COMMENT ON COLUMN public.user.gender IS ‘性別’;
COMMENT ON COLUMN public.user.age IS ‘年齡’;
COMMENT ON COLUMN public.user.id_no IS ‘身份證號(hào)’;
COMMENT ON COLUMN public.user.created_date IS ‘創(chuàng)建時(shí)間’;
COMMENT ON COLUMN public.user.created_by IS ‘創(chuàng)建人’;
COMMENT ON COLUMN public.user.updated_date IS ‘更新時(shí)間’;
COMMENT ON COLUMN public.user.update_by IS ‘更新人’;

— 主鍵 （如果建表語(yǔ)句里面沒(méi)添加主鍵就執(zhí)行該語(yǔ)句）
alter table public.user
add constraint user_pkey primary key (id);

— 索引或唯一索引
drop index if exists user_name;
CREATE INDEX user_name ON user (name);

drop index if exists user_id_no;
CREATE UNIQUE INDEX user_id_no ON user (id_no);

— 授權(quán)
GRANT ALL ON TABLE public.user TO mydata;
GRANT SELECT, UPDATE, INSERT, DELETE ON TABLE public.user TO mydata_dml;
GRANT SELECT ON TABLE public.user TO mydata_qry;
