ทำอย่างไรให้สามารถดึงข้อมูล $BARCODE ทั้งหมดจากฐานข้อมูลมาแสดงเป็น 8 คอลัมภ์ได้บ้างครับ
--
-- ฐานข้อมูล`

Create Database Data;
CREATE TABLE `book` (
`IDBOOK` int(6) NOT NULL auto_increment,
`BARCODE` varchar(10) NOT NULL,
`BNAME1` varchar(35) default NULL,
PRIMARY KEY (`IDBOOK`)
) ENGINE=MyISAM DEFAULT CHARSET=tis620 AUTO_INCREMENT=123463 ;
--
-- dump ตาราง `book`
--
INSERT INTO `book` VALUES (1, '423000001','ชื่อหนังสือ1');
INSERT INTO `book` VALUES (2, '423000002', 'ชื่อหนังสือ2');
INSERT INTO `book` VALUES (3, '423000003','ชื่อหนังสือ3');
