我运行下面的sql脚本在我的数据库:
create table cities (
id serial primary key,
name text not null
);
create table reports (
id serial primary key,
cityid integer not null references cities(id),
reportdate date not null,
reporttext text not null
);
create user www with password 'www';
grant select on cities to www;
grant insert on cities to www;
grant delete on cities to www;
grant select on reports to www;
grant insert on reports to www;
grant delete on reports to www;
grant select on cities_id_seq to www;
grant insert on cities_id_seq to www;
grant delete on cities_id_seq to www;
grant select on reports_id_seq to www;
grant insert on reports_id_seq to www;
grant delete on reports_id_seq to www;
当用户www试图:
insert into cities (name) values ('London');
我得到以下错误:
ERROR: permission denied for sequence cities_id_seq
我知道问题出在连续类型上。这就是为什么我将*_id_seq的选择、插入和删除权限授予www。但这并不能解决我的问题。我错过了什么?
