这里用一个实例来演示PostgreSQL存储过程如何返回数据集。

1、首先准备数据表

//member_category
create table member_category(id serial, name text, discount_rate real, base_integral integer);
alter table member_category add primary key(id);
alter table member_category add check(name<>”);

//member
create table member(id serial, member_num text, name text, category_id integer, account numeric(16,2), integral integer, phone text, birthday date, qq integer, email text, status integer, address text, tip text, start_date date, valid_date integer, password text, creator integer, store_name text);
alter table member add primary key(id);
alter table member add foreign key(creator) references employee;
alter table member add foreign key(category_id) references member_category;
alter table member add  onaccount int;

alter table member add &nbsp;onaccount int;
alter table member add &nbsp;store_name text;
