Are these two INNER JOINS the same?

[lordvader]

I'm exploring inner joins. This guy's wordpress plugin code has an inner join like this:

FROM (((($wpdb->posts INNER JOIN $wpdb->term_relationships ON $wpdb->posts.ID = $wpdb->term_relationships.object_id)
INNER JOIN $wpdb->term_taxonomy ON $wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
INNER JOIN $wpdb->terms ON $wpdb->term_taxonomy.term_id = $wpdb->terms.term_id))

 

So I'm wondering if that's the same as:

FROM $wpdb->posts
INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id)
INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
INNER JOIN $wpdb->terms ON ($wpdb->term_taxonomy.term_id = $wpdb->terms.term_id)

 

thx

Yes, all those extra parens do nothing in this case.
