B_Dark on "MySQL Query: How do I take off what a field has and add it to another one?"

After I found which ones correspond with a column (meta_key "address") of the table wp_postmeta..

SELECT * FROM wp_posts
LEFT JOIN wp_postmeta
ON wp_posts.ID = wp_postmeta.post_id
WHERE wp_postmeta.meta_key = 'address'

I want to take(and leave nothing there) from the column "meta_value" everything that is registered to and add it to the column "post_content" that is on the table "wp_post".

In every corresponding "post_content" are many thing registered and I don't want to lose them, I want whatever it takes from "meta_value" to just add it at the end of every input that is in every "post_content". Is this possible?
