Hi all

$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (1, 'Sex Activities', 1254009600, 1254009600)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (2, 'Super Markets', 1282521600, 1282521600)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (3, 'WiFi Spots', 1281484800, 1281484800)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (4, 'Ακτοπλοϊκές Εταιρείες', 1284336000, 1284336000)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (5, 'Αρχείο Σημείων', 1269475200, 1269475200)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (6, 'Αρώματα-Ομορφιά-Κομμωτήρια', 1282089600, 1282089600)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (7, 'Αυτοκίνητα', 1284681600, 1284681600)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (8, 'Βενζινάδικα', 1284249600, 1284249600)");
$db->query_write("INSERT INTO `" . TABLE_PREFIX . "mytable` VALUES (9, 'Βιβλία-Χαρτικά', 1284681600, 1284681600)");

}

?>
the lines 1,2,3 import ok

at the lines 4,5,6,7,8,9 in second field put nothing and not the data from insert command !!!

Any Idea?????

Maybe I'm just stating the obvious, but it seems the greek characters are causing the problem, so it's an issue with character set configuration somewhere.
