php – INSERT ON DUPLICATE KEY UPDATE语句的复杂mysql查询错误

对于我正在开发的Web应用程序,我有一个非常复杂的SQL语句.哪个以前工作过.但我无法弄清楚改变了什么..

sql错误：

“You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ON DUPLICATE KEY UPDATE bankaccountid = VALUES(bankaccountid), ownerid = VALUES(‘ at line 1″

我的查询是：

<?php
if($bank_name1 !== '') {
        $bank1 = "('$bank_id1', '$owner_id', '$ownertype1', '$accounttype1', '$currency1', '$bank_name1', '$bank_loc1', '$bank_country1', '$bank_accountno1', '$bank_sortcode1', '$bank_iban1', '$bank_bicswift1', '$secondary1'),";
    } else {
        $bank1 = '';
    }

    if($bank_name2 !== '') {
        $bank2 = "('$bank_id2', '$owner_id', '$ownertype2', '$accounttype2', '$currency2', '$bank_name2', '$bank_loc2', '$bank_country2', '$bank_accountno2', '$bank_sortcode2', '$bank_iban2', '$bank_bicswift2', ''),";
    } else {
        $bank2 = '';
    }

    if($bank_name3 !== '') {
        $bank3 = "('$bank_id3', '$owner_id', '$ownertype3', '$accounttype3', '$currency3', '$bank_name3', '$bank_loc3', '$bank_country3', '$bank_accountno3', '$bank_sortcode3', '$bank_iban3', '$bank_bicswift3', '$secondary3'),";
    } else {
        $bank3 = '';
    }

    if($bank_name4 !== '') {
        $bank4 = "('$bank_id4', '$owner_id', '$ownertype4', '$accounttype4', '$currency4', '$bank_name4', '$bank_loc4', '$bank_country4', '$bank_accountno4', '$bank_sortcode4', '$bank_iban4', '$bank_bicswift4', '')";
    } else {
        $bank4 = '';
    }

    $sql = "INSERT INTO bankaccounts (bankaccountid, ownerid, ownertype, accounttype, currency, bankname, location, bankcountry, accountno, sortcode, iban, bicswift, secondary) VALUES ".$bank1." ".$bank2." ".$bank3." ".$bank4." ON DUPLICATE KEY UPDATE bankaccountid = VALUES(bankaccountid), ownerid = VALUES(ownerid), ownertype = VALUES(ownertype), accounttype = VALUES(accounttype), currency = VALUES(currency), bankname = VALUES(bankname), location = VALUES(location), bankcountry = VALUES(bankcountry), accountno = VALUES(accountno), sortcode = VALUES(sortcode), iban = VALUES(iban), bicswift = VALUES(bicswift), secondary = VALUES(secondary)";

我现在已经重新阅读了这个查询一小时了……我一定是错过了一些相当愚蠢的东西……

这是原始SQL查询：

INSERT INTO bankaccounts (bankaccountid, ownerid, ownertype, accounttype, currency,
    bankname, location, bankcountry, accountno, sortcode, iban, bicswift, secondary)
    VALUES ".$bank1." ".$bank2." ".$bank3." ".$bank4."
ON DUPLICATE KEY UPDATE bankaccountid = VALUES(bankaccountid),
    ownerid = VALUES(ownerid), ownertype = VALUES(ownertype),
    accounttype = VALUES(accounttype), currency = VALUES(currency),
    bankname = VALUES(bankname), location = VALUES(location),
    bankcountry = VALUES(bankcountry), accountno = VALUES(accountno),
    sortcode = VALUES(sortcode), iban = VALUES(iban),
    bicswift = VALUES(bicswift), secondary = VALUES(secondary)

只要查询的UPDATE部分为真,一切都可以.但是当我尝试INSERT时,我得到了mysql抛出的错误.

解决方法:

我把它添加到顶部

$bank_name1="b1";
$bank_name2="b2";
$bank_name3="b3";
$bank_name4="b4";

这到底

echo $sql;

这是你的字符串：

INSERT INTO bankaccounts (bankaccountid, ownerid, ownertype, accounttype, currency, bankname, location, bankcountry, accountno, sortcode, iban, bicswift, secondary) 
VALUES ('', '', '', '', '', 'b1', '', '', '', '', '', '', ''), 
('', '', '', '', '', 'b2', '', '', '', '', '', '', ''), 
('', '', '', '', '', 'b3', '', '', '', '', '', '', ''), 
('', '', '', '', '', 'b4', '', '', '', '', '', '', '') 

ON DUPLICATE KEY UPDATE bankaccountid = VALUES(bankaccountid), ownerid = VALUES(ownerid), ownertype = VALUES(ownertype), 
accounttype = VALUES(accounttype), currency = VALUES(currency), bankname = VALUES(bankname), location = VALUES(location), 
bankcountry = VALUES(bankcountry), accountno = VALUES(accountno), sortcode = VALUES(sortcode), iban = VALUES(iban), 
bicswift = VALUES(bicswift), secondary = VALUES(secondary)

那是一场等待发生的爆炸. Update部分不应包含VALUES()包装器.

相反,UPDATE部分应遵循以下形式：

update col1=someval1,col2=someval2, ...
