SQL语法错误，我可以'；找不到错误 - error in SQL syntax, I can't find the error

error in SQL syntax, I can't find the error

尝试了3个小时后，我找不到错误。有人能帮我吗？

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=的时候

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；在第1行的"ProductBarcode=，ProductPakking=，ProductPresent=，ProductMinimuim="附近，请查看与MySQL服务器版本对应的手册，以获得要使用的正确语法

我假设$ProductName不是整数，所以你需要在这里用引号括起来：

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

另外，请注意，不应该将变量串联成这样的字符串。请参阅这篇文章，了解情况有多糟。

更新的SQL语句请不要使用THIS，BIND VARIABLES INSTEAD：

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;
