Hey.
 I'm currently learning to use MySql and have a couple of questions.

1) How do I update a column (empty table) to make it an AUTO\_INCREMENT column? I tried

```
ALTER TABLE book UPDATE id AUTO_INCREMENT;

```

but I get an SQL Syntax error.

2) If I add a new column, how can I change its position in the table? For example, if I add a new column, it's added to the end. What if I want to move it to the beginning? 

Thanks
