MYSQL插入表中，将id从temp_tbl中选择为NULL，*

Question

I would like to select everything from a temporary table then set the id of the result to NULL so that I can insert this record to a table like below:

insert into product select NULL as id, * from tmp_tb

But this query does not work. Please give me an idea how to do this correctly. Thanks in advance!
