How to copy a table and add a field with MySQL?

Question

I would like to copy a table A into a table B with INSERT ... SELECT without declaring all fields in MySQL.

But the issue is my table B has an auto-increment field at the beginning called id:

table_A

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

table_B

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

I tried to do something like:

INSERT INTO table_B SELECT auto, * FROM table_A

But it didn't work. What is the best solution?

Answer 1

Specify the column names explicitly:

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

or even

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

Answer 2

You no need to worry to generate a value for id column in Table_B while inserting records from Table_A.

Because Auto_Incerement columns are like column which have default value. The difference is only that the default value is increased by some specified interval from the last inserted value in that column.
