$order = new Application_Model_DbTable_Order();
$orderno = $order->select()
->from($order, 'orderno')
->where('memberid = ?', $userid)
->order('orderno DESC')
->limit(1, 0);
SQLSTATE[HY000]:一般错误:1366 整数值不正确:'SELECT
ordertable
.orderno
FROMordertable
WHERE (memberid = '30') ORDER BYorderno
DESC LIMIT 1' 用于第 1 行的列 'orderno'
收到此错误,我想知道我的代码是否有任何问题,因为我到处寻找原因,但似乎没有找到任何帮助。
#SQL code for Ordertable#
`orderno` int(5) NOT NULL AUTO_INCREMENT,
`memberid` int(5) DEFAULT NULL,
PRIMARY KEY (`orderno`)
#SQL code for Item#
`itemid` int(5) NOT NULL AUTO_INCREMENT,
`image` varchar(100) NOT NULL,
`itemname` varchar(30) DEFAULT NULL,
`description` varchar(100) DEFAULT NULL,
`itemtype` varchar(20) DEFAULT NULL,
PRIMARY KEY (`itemid`)
#SQL code for Orderdetail#
`orderdetailno` int(5) NOT NULL AUTO_INCREMENT,
`orderno` int(5) NOT NULL,
`itemid` int(5) NOT NULL,
`unitcost` decimal(6,2) DEFAULT NULL,
PRIMARY KEY (`orderdetailno`),
KEY `orderno` (`orderno`),
KEY `itemid` (`itemid`)
如果它有助于我使用 MySQL,这是我的 sql 代码。
$request = new Zend_Session_Namespace('cart');
$auth = Zend_Auth::getInstance();
$user = $auth->getIdentity();
$userid = $user->userid;
$order = new Application_Model_DbTable_Order();
$itemdb = new Application_Model_DbTable_Item();
$orderdetail = new Application_Model_DbTable_Orderdetail();
$data = array ('memberid' => $userid);
$order->insert($data);
$orderno = $order->select()
->from($order, 'orderno')
->where('memberid = ?', $userid)
->order('orderno DESC')
->limit(1, 0);
foreach ($request->array as $var)
{
$unitprice = $itemdb->select()
->from('$itemdb', 'unitcost')
->where('itemid = ?', $var);
$newArray = array('orderno' => $orderno,
'itemid' => $var,
'unitcost' => $unitprice, );
$orderdetail->insert($newArray);
}
任何指导将不胜感激。
