t-SQL to allow comments and ping backs on all your posts
If you want to update all of your posts in your Word Press blog site from closed commentsand closed pingbacks, then you can run this update script to update all of your posts to allow comments and pingbacks. Log in to your PHPMyAdmin where your database for your site lives, select the database, then select Query and insert the following, then click Go. :)
UPDATE wp_posts SET Comment_Status = 'open',Ping_Status = 'open' WHERE ID > 0
NOTE: Now, sometimes, when these SQL queries are placed in block-quotes, the single quotes get all weird and you might have to re-type them.
