insert select mysql复制表数据方法

To copy data from one table to another in MySQL, you can use the INSERT INTO SELECT statement. Here is an example:

Suppose you have two tables named “table1” and “table2” and you want to copy all the data from “table1” to “table2”. You can do so using the following SQL query:

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1;
    

In this query, you need to replace “column1, column2, column3, …” with the actual column names of the tables. This query will insert all the data from “table1” into “table2”.
