如何复制表格并添加 MySQL 字段?
原标题:How to copy a table and add a field with MySQL?

我想将表格“强”A " / " 强 " 复制到有 INSERT.SELECT 的表格 " 强 " B " / " 强 " 上,但没有在 MySQL 中宣布所有字段。

但问题是我的表B在开头有一个自动递增字段,叫做id :

< 坚固> 表格_A

 name    age      etc
-------|--------|--------|
 abc   | 28     | ...    |

< 强度 > 表格_B

 id      name    age      etc
-------|-------|--------|--------|

我试图做一些事情,比如:

INSERT INTO table_B SELECT auto, * FROM table_A

但它没有奏效。什么是最好的解决办法?

最佳回答

明确指定列名称:

INSERT INTO table_B (name,age,etc) SELECT * FROM table_A

或 偶 或

INSERT INTO table_B (name,age,etc) SELECT name,age,etc FROM table_A
问题回答

在插入表_A的记录时,无需在表_B中为id列生成值。

因为 Auto_Incerement 列与有默认值的列相似。 不同的是, 默认值会比该列中最后一个插入值增加一定的间隔 。
