Is there a mysql command that can alter a table so that my column (owner) can have the same values as the primary key (id)? 

This is basically what I want:

```
id  |  title  |  body  |  owner | 
----------------------------------
1                          1
2                          2   
3                          3
4                          4

```

I want this to be automatic so that I don't have to find the "id" value and then insert that value into the owner column using php. I'm planning on using the "owner" column as a foreign key. 

Note: The id column is the primary key, and has auto increment.

Thanks everyone (:
