MYSQL:如何在mysql中将整个行从一个表复制到另一个表，而第二个表又增加一列? [英] MYSQL: How to copy an entire row from one table to another in mysql with the second table having one extra column?

问题描述

除了一列外，我有两个结构相同的表.表2还有另外一列，我将在其中插入CURRENT_DATE()

I have two tables with identical structure except for one column... Table 2 has that additional column in which i would insert the CURRENT_DATE()

我想将所有值从table1复制到table2.

I would like to copy all the values from table1 to table2.

如果我使用

INSERT INTO dues_storage SELECT * FROM dues WHERE id=5;

它抛出一个错误，指出列数的差异.

it throws an error pointing out to the difference in the number of columns.

对此我有两个问题:

1. 我该如何解决?
2. 以及如何在同一条语句的表2中添加附加日期列(CURRENT_DATE())的值?
