参数化插入...重复键UPDATE失败使用SET语义

我有一个存储客户端信息的数据库。我有一个独特的电话号码字段叫“电话”。我试图使用参数化查询插入到表中，并在重复键上更新客户端信息。我已经四次检查拼写，并且所有内容都达到了标准。我不断收到错误“检查...在WHERE附近使用正确的语法`Phone` =？”参数化插入...重复键UPDATE失败使用SET语义

// These are the fields that we want to Upsert 
$fields = " 
    `Objectives` = :objectives, 
    `LiquidFunds` = :liquidFunds, 
    `UnitNumber` = :unitNumber, 
    `Accredited` = :accredited, 
    `FirstName` = :firstName, 
    `LastName` = :lastName, 
    `Street`  = :street, 
    `Phone`  = :phone, 
    `Email`  = :email, 
    `State`  = :state, 
    `Notes`  = :notes, 
    `City`  = :city, 
    `Zip`   = :zip 
"; 



$updateLead = $dbHandle -> prepare(" 
    INSERT INTO `Leads` SET $fields 
    ON DUPLICATE KEY UPDATE $fields WHERE `Phone` = :phoneKey" 
);

后来我绑定的参数，像这样

// Bind our parameters to the updateLead query 
$updateLead -> bindParam(":objectives" , $objectives); 
$updateLead -> bindParam(":liquidFunds", $_POST['liquidFunds']); 
$updateLead -> bindParam(":unitNumber" , $_POST['unitNumber']); 
$updateLead -> bindParam(":accredited" , $_POST['accredited']); 
$updateLead -> bindParam(":firstName" , $_POST['fname']); 
$updateLead -> bindParam(":lastName" , $_POST['lname']); 
$updateLead -> bindParam(":street"  , $_POST['street']); 
$updateLead -> bindParam(":phone"  , $_POST['phone']); 
$updateLead -> bindParam(":phoneKey" , $_POST['phone']); 
$updateLead -> bindParam(":email"  , $_POST['email']); 
$updateLead -> bindParam(":state"  , $_POST['state']); 
$updateLead -> bindParam(":notes"  , $_POST['notes']); 
$updateLead -> bindParam(":city"  , $_POST['city']); 
$updateLead -> bindParam(":zip"  , $_POST['zip']);

这个确切结构完美的作品，如果我更改查询到

$updateLead = $dbHandle -> prepare("UPDATE `Leads` SET $fields WHERE `Phone` = :phoneKey);

我试图把一切都在同一个行，它会抛出相同的错误（只是在不同的“行号”上）。我在这里做错了什么？

PS：我使用PHP/PDO

也许是阅读一些关于'DUPLICATE KEY UPDATE'的手册？ –

我不确定我是否遵循 –

原来的问题是，我不得不在查询重复占位符的事实。我改变它到这

// These are the fields that we want to Upsert 
$fields = " 
    `Objectives` = :objectives, 
    `LiquidFunds` = :liquidFunds, 
    `UnitNumber` = :unitNumber, 
    `Accredited` = :accredited, 
    `FirstName` = :firstName, 
    `LastName` = :lastName, 
    `Fronter`  = :fronter, 
    `Street`  = :street, 
    `Phone`  = :phone, 
    `Email`  = :email, 
    `State`  = :state, 
    `Notes`  = :notes, 
    `City`  = :city, 
    `Zip`   = :zip 
"; 

$updateFields = " 
    `Objectives` = VALUES(Objectives), 
    `LiquidFunds` = VALUES(LiquidFunds), 
    `UnitNumber` = VALUES(UnitNumber), 
    `Accredited` = VALUES(Accredited), 
    `FirstName` = VALUES(FirstName), 
    `LastName` = VALUES(LastName), 
    `Fronter`  = VALUES(Fronter), 
    `Street`  = VALUES(Street), 
    `Phone`  = VALUES(Phone), 
    `Email`  = VALUES(Email), 
    `State`  = VALUES(State), 
    `Notes`  = VALUES(Notes), 
    `City`  = VALUES(City), 
    `Zip`   = VALUES(Zip) 
"; 


$updateLead = $dbHandle -> prepare(" 
    INSERT INTO `Leads` SET $fields 
    ON DUPLICATE KEY UPDATE $updateFields 
");

它的工作！

相同的占位符可以。你的问题是这个查询不支持'WHERE'。 –

真的吗？....为什么呢，如果我可以？ MySQL会自动知道哪一行更新？（这样做是有道理的......）。无论如何，我删除了WHERE子句，以及：phoneKey参数。我收到“无效的参数数量”错误。我会继续挖掘。谢谢你的小费 –

你的'Phone'列是唯一的--MySQL绝对知道哪个记录拥有这个值 –
