<p>I am seeting up Apache server with TortoiseSVN for local source code repository. Currently on trial purpose I am setting only two users.

| <p>The main reason you might want to do this on subversion is for binary files (i.e. images, etc.) that are difficult or impossible to 'merge'. In those cases, each user can request a lock on a file.

<p>I tried this in mysql:</p>
<pre><code>mysql> alter table region drop column country_id;
