Problema con left Joins

[saulmty]

La verdad no, por que no necesito el max de las ligas, de todas formas ya resolvi la situacion con una query anidada, la anexo :

Select wp_links.link_id, wp_links.link_url, wp_links.link_name, wp_links.link_image, wp_links.link_description, wp_links.link_target,
wp_links.link_category, wp_links.link_size, wp_links.post_cat, wp_posts.ID, wp_posts.post_title,
wp_posts.post_excerpt, wp_posts.post_content, wp_posts.guid, autolinks.autodias, wp_links.link_rating, wp_categories.cat_name, wp_categories.category_description
FROM wp_links
LEFT JOIN ( SELECT MAX(post_id) AS post_id, category_id FROM wp_post2cat GROUP BY category_id )
AS post ON wp_links.post_cat = post.category_id
LEFT JOIN wp_posts ON post.post_id = wp_posts.ID
LEFT JOIN autolinks ON wp_links.link_id = autolinks.id_link
LEFT JOIN wp_categories ON wp_categories.cat_ID = post.category_id
WHERE wp_links.link_visible = 'Y'
AND (wp_links.link_category = 1 or wp_links.link_category = 2)
ORDER BY wp_links.link_category ASC, wp_links.link_rating ASC

Saludos y gracias.
