export list from posts: problem “guid”

My problem:

I must export a list from table “posts” with only two column, post_author and guid (the url of article) but in the export list I find many record with this text in the guid: “http://www.site.com/?p=3629″. All the article must have guid =”http://www.site.com/name_article.html”.

For example the article with id=3629 is publis and the data are:

(ID, post_author, post_date, post_date_gmt, post_content, post_title, post_category, post_excerpt, post_status, comment_status, ping_status, post_password, post_name, to_ping, pinged, post_modified, post_modified_gmt, post_content_filtered, post_parent, guid, menu_order, post_type, post_mime_type, comment_count) VALUES (3629, 1, ‘2008-12-06 14:59:06’, ‘2008-12-06 15:59:06’, ‘xxxxxxxxxxx’ /></div></br>’, ‘xxxxxxxxxxx’, 0, ”, ‘publish’, ‘open’, ‘open’, ”, ‘xxxxxxxxx’, ”, ”, ‘2008-12-06 15:33:57’, ‘2008-12-06 16:33:57’, ”, 0, ‘http://www.site.com/?p=3629&#8217;, 0, ‘post’, ”, 0);

I’ve setting my wp with permalink: /%postname%-%post_id%.html

What’s the problem?

thanks and sorry for my english
