Joining WordPress Comments with Post Titles from MySQL DB


I'm working with a wordpress database and need to get some data on the comments.


The goal is to get comments from a decommissioned site. I have the database running on my local system and can generate a report from the wp_comments table easy enough. That table has a column named 'comment_post_id' which is a direct correlation to the ID column in the wp_posts table.


I've dumped both from mysql into excel and done a vlookup from the comments table into the posts table to get the desired report.


While the dump->excel process works, I know this could probably be done with a query in mysql.


My first crack at it fails:



SELECT * FROM 'wp_posts' WHERE ('wp_comments.comment_post_id' = 'wp_posts.id');


and doesn't even include a join yet.


Can you provide any pointers or tips on getting a correct query?


Thank you.
