i can confirm that. BertrandB’s solution is working indeed. the dateupdate-script posted by justin above does not help. with the integer-casts i solved the broken page-archive due to wrong string vs. integer comparison – like bertrandb already said it: ’08′ != 8

thanks bertrand, now i have my page-archive finally working

Ok i’ll wait, for the moment my fix (with the cast) solve my problem as you can see my worrd works fine

and i don’t see errors in my database with SqliteManager i have
post_date = ’2008-08-30 18:30:12′
the problem that yoiy patch fix is for the first day of a month and in my database the post_date is right like this
’2008-09-04 21:36:03′ i think that we don’t speak of same problem mine was because ’08′ is not equal to 08 (the string is not equal to the integer.

the code above was flawed. i’ve fixed it now.
i’m also going to have a look at the stringify option for pdo which would then more closely mimic the mysql behaviour and thus might avoid some other problems i’ve been seeing.

oh, and you might want to fix the existing inconsistencies in the database from previous posts. don’t forget to backup your database first!

i wrote this code, which should work but I HAVE NOT TESTED IT other than on a tiny wp installation.

I store this file in the wp root directory (don’t forget to remove it after use…)


ini_set('display_errors', true);
error_reporting(E_ALL);
 
$array[] = 
array (	'table'=>	'wp_comments',
		'fields'=>	array(	'comment_date', 
							'comment_date_gmt')	
		);
$array[] = 
array (	'table'=>	'wp_links',
		'fields'=>	array(	'link_updated')	
		);
$array[] = 
array (	'table'=>	'wp_posts',
		'fields'=>	array(	'post_date',
							'post_date_gmt',
							'post_modified',
							'post_modified_gmt',
							)
		);
$array[] = 
array (	'table'=>	'wp_users',
		'fields'=>	array(	'user_registered')
		);
try {
	$wpdb = new PDO('sqlite:./wp-content/database/MyBlog.sqlite'); 
} catch (Exception $e) {
	echo $e->getMessage();
	exit;
}
 
$wpdb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
$wpdb->sqlitecreatefunction('rewriteDates', 'rewriteDates', 1);
 
function rewriteDates($string){
	$pattern = '/([12]d{3})-(d{1,2})-(d{1,2})/ims';
	return preg_replace_callback($pattern, '_rewriteDates', $string);
 
}
function _rewriteDates($date){
	list ($all, $year, $month, $day) = $date;
	$return = sprintf("%s-%02s-%02s", $year, $month, $day);
	echo $return . "
";
	return $return;
}
foreach ($array as $query){
	$q = "Update $query[table] set ";
	foreach ($query['fields'] as $field){
		$q .= "$field = rewriteDates($field),";
	}
	$q = rtrim($q, ',');
        $wpdb->exec($q);
}
 
echo 'Finished';
