Question

尝试3小时后我找不到错误。有人可以帮我吗？

这是我的查询=

$query = "INSERT INTO `card`(ProductName,ProductBarcode,ProductPakking,ProductPresent,ProductMinimuim,FotoUrl,DBid) SELECT * FROM (SELECT '" . $ProductName . "','" . $ProductBarcode . "','" . $ProductPakking . "','" . $ProductPresent . "','" . $ProductMinimuim . "','" . $FotoUrl . "','" . $DBid ."') AS tmp WHERE NOT EXISTS (SELECT name FROM `card` WHERE `ProductName` = " . $ProductName . ",`ProductBarcode` = " . $ProductBarcode . ",`ProductPakking` = " . $ProductPakking . ",`ProductPresent` = " . $ProductPresent . ",`ProductMinimuim` = " . $ProductMinimuim . ",`FotoUrl` = " . $FotoUrl . ",`DBid` = " . $DBid ." ) LIMIT 1;";

这是我回显我的查询=

INSERT INTO `card`(ProductName,ProductBarcode,ProductPakking,ProductPresent,ProductMinimuim,FotoUrl,DBid)
SELECT * FROM (
    SELECT 'brood','8717333541583','zak','-1937','11','img/img.svg','3') AS tmp
WHERE NOT EXISTS (
    SELECT name FROM `card` WHERE
        `ProductName` = 'brood',
        `ProductBarcode` = '8717333541583',
        `ProductPakking` = 'zak',
        `ProductPresent` = '-1937',
        `ProductMinimuim` = '11',
        `FotoUrl` = 'img/img.svg',
        `DBid` = '3' )
) LIMIT 1

错误您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在第1行“ProductBarcode =，ProductPakking =，ProductPresent =，ProductMinimuim ='附近使用正确的语法< / p>

我假设$ProductName不是整数，因此您需要在引号中包含它：

WHERE `ProductName` = '" . $ProductName . "'

另外，请注意，您不应该将变量连接成类似的字符串。有关这有多糟糕的信息，请参阅this post。

更新后的SQL语句请不要使用此内容，绑定变量：

INSERT INTO `card`(ProductName,ProductBarcode,ProductPakking,ProductPresent,ProductMinimuim,FotoUrl,DBid)
SELECT * FROM (
    SELECT '" . $ProductName . "','" . $ProductBarcode . "','" . $ProductPakking . "','" . $ProductPresent . "','" . $ProductMinimuim . "','" . $FotoUrl . "','" . $DBid ."') AS tmp
WHERE NOT EXISTS (
    SELECT ProductName FROM `card` WHERE
        `ProductName` = '" . $ProductName . "' AND
        `ProductBarcode` = '" . $ProductBarcode . "' AND
        `ProductPakking` = '" . $ProductPakking . "' AND
        `ProductPresent` = '" . $ProductPresent . "' AND
        `ProductMinimuim` = '" . $ProductMinimuim . "' AND
        `FotoUrl` = '" . $FotoUrl . "' AND
        `DBid` = '" . $DBid ."'
) LIMIT 1;

SQL语法错误，我找不到错误
