Sqlite 导入后更新序列值

我定义了一个

串行主键

，如下所示：

CREATE TABLE auth_event(
    id serial PRIMARY KEY,
    time_stamp TIMESTAMP,
    client_ip VARCHAR(512),
    user_id INTEGER REFERENCES auth_user (id) ON DELETE CASCADE,
    origin VARCHAR(512),
    description TEXT
);

INSERT INTO "auth_event" VALUES(6,'2012-12-03 21:50:49','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(7,'2012-12-04 07:37:43','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(8,'2012-12-05 11:42:28','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(9,'2012-12-07 08:01:59','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(10,'2012-12-07 16:32:58','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(11,'2012-12-11 15:41:24','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(12,'2012-12-11 22:55:08','127.0.0.1',181,'auth','User 181 Logged-in');

我要导入的转储具有串行字段的显式值，如下所示：

CREATE TABLE auth_event(
    id serial PRIMARY KEY,
    time_stamp TIMESTAMP,
    client_ip VARCHAR(512),
    user_id INTEGER REFERENCES auth_user (id) ON DELETE CASCADE,
    origin VARCHAR(512),
    description TEXT
);

INSERT INTO "auth_event" VALUES(6,'2012-12-03 21:50:49','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(7,'2012-12-04 07:37:43','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(8,'2012-12-05 11:42:28','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(9,'2012-12-07 08:01:59','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(10,'2012-12-07 16:32:58','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(11,'2012-12-11 15:41:24','127.0.0.1',181,'auth','User 181 Logged-in');
INSERT INTO "auth_event" VALUES(12,'2012-12-11 22:55:08','127.0.0.1',181,'auth','User 181 Logged-in');

这意味着，根据这一点，序列值（与

auth_event.id

）将不会得到更新

现在我的问题来了：我使用的框架没有给串行字段赋值。这意味着postgres正在使用默认值，并且由于该值尚未更新，因此会发生冲突

导入后如何更新与

auth_event.id

相关的序列值？

几乎不需要“+1”。序列在返回下一个值之前递增。；）@库林：你确定吗？我在其他地方看到过使用+1（）只是为了验证：如何获取某个序列的当前值？我已经尝试过：

select currval（pg_get_serial_sequence（'auth_event'，'id'）它只给出：
错误：序列“auth_event_id_seq”的当前值在此会话中尚未定义
确定，因此我这里的问题的答案似乎是否定的：我无法获得序列的当前值（不修改它）。这是正确的吗？
select setval(pg_get_serial_sequence('auth_event' , 'id'), (select max(id) from auth_event) );
