如何防止主串行主键被不按顺序更新的数字?

问题描述

CREATE TABLE u_account (
Jid serial primary key,
score int4
);

当我这样更新主键时，主键工作正常(可以自行更新)；

The primary key works fine (updates itself) ok when I update it like this;

INSERT INTO u_account ('score') VALUES ('122233344');

但是当我插入这样的值时；

However when I insert a value like this;

INSERT INTO u_account VALUES ('122233344');

这将更新主键；

我不希望主键接受除了应该输入的数字之外的其他任何东西.

I don't want the primary key to accept anything other than the number that is supposed to be coming next.

以前有人为我设置了它，以便我输入这段代码；

Someone had set it up for me before so that if I put in this code;

INSERT INTO u_account VALUES ('122233344');

它将忽略主键，仅更新分数.

it would ignore the primary key and just update score.

请帮助.

推荐答案

您可以使用"DEFAULT"在主键字段中输入正确的值，例如:

You can use "DEFAULT" to put the correct value in the primary key field, eg:

INSERT INTO u_account VALUES (DEFAULT, '122233344');
