INSERT SQL - Clone a column in MySQL

It is possible to use two SQL syntaxes to copy data from one table in the database to another:

The first syntax if the two tables have the same schema:

INSERT INTO table2
SELECT * FROM table1

Otherwise, You must specify the column names you want to copy (the column list is optional for 'table2' if you are specifying a value for all columns and selecting the columns in the same schema order of 'table2'.

INSERT INTO table2(col1, col2, col3)
SELECT col1, col2, col3
FROM table1
