PostgreSQL通过SQL语句创建表结构

在没有图形客户端，或图形客户端比较难用时，可以直接使用SQL语句来创建PostgreSQL的建表语句，下面以具体的创建user表的语句来进行演示。

建表语句：

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);

字段添加注释：

COMMENT ON TABLE public.user IS '用户表';
COMMENT ON COLUMN public.user.id IS '主键';
COMMENT ON COLUMN public.user.name IS '姓名';
COMMENT ON COLUMN public.user.gender IS '性别';
COMMENT ON COLUMN public.user.age IS '年龄';
COMMENT ON COLUMN public.user.id_no IS '身份证号';
COMMENT ON COLUMN public.user.created_date IS '创建时间';
COMMENT ON COLUMN public.user.created_by IS '创建人';
COMMENT ON COLUMN public.user.updated_date IS '更新时间';
COMMENT ON COLUMN public.user.update_by IS '更新人';

主键

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);

授权

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;
