Does anyone know how I can fix this? Error:

MySQL error!

Duplicate entry '0' for key 1(Errno=1062)

Your query: Insert New Post

INSERT INTO evo_posts( post_author, post_title, post_urltitle, post_content,
                            post_issue_date, post_mod_date, post_category,  post_status, post_locale,
                            post_url, post_autobr, post_flags, post_wordcount,
                            post_comments, post_renderers )
            VALUES( 1, 'Hello',
                    'hello',
                    'This is a MySQL error.',
                    '2006-05-15 19:40:26',
                    '2006-05-15 19:40:26',
                    18,
                    'published',
                    'en-US',
                    '',
                    '0',
                    'pingsdone',
                    5,
                    'open',
                    'b2evGMco.b2evALnk.b2WPAutP.b2evSmil' )

I don't have PHPMyAdmin, so something through raw MySQL would be good. Thanks for any help.
