如何在只有一个自动增量列的表中插入一行? [英] How to insert a row into a table that has only a single autoincrement column?

问题描述

我的表只有一个称为 id 的列.此列是一个自动递增的键(我正在使用它进行排序).我想做类似的事情:insert into sequencer;但这给我SQL错误，因为我想我需要有一个values部分.但是表中没有其他列，我希望 id 列自动递增.我也不想仅仅通过添加另一个虚拟列来破解它.谢谢.

My table has only a single column calld id. This column is an autoincrementing key (I am using it for sequencing). I want to do something like: insert into sequencer; but this gives me SQL errors because I guess I need to have a values portion. But there are no other columns in the table and I want the id column to be autoincremented. I'd also rather not hack this by just adding another dummy column. Thanks.

推荐答案

INSERT INTO table SET id = NULL;

或

INSERT INTO table VALUES (NULL);

在自动增量列中插入NULL时，mysql将改为生成一个新数字.

When inserting NULL into an auto-increment column, mysql will generate a new number instead.
