I need to copy the contents of key value for the key post_content to another table called wp_posts into the key values for post_content.
Is there anyway to do this in bulk, like all posts in the database? This would help me greatly, thank you.
Assuming your first post_content is in wp_postmeta (a custom field). Then you would copy from the wp_postmeta to the wp_posts;
UPDATE wp_posts,wp_postmeta SET wp_posts.post_content = wp_postmeta.meta_value WHERE wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key='abstract'
