更新在MySQL的PHP​​ Pdo不工作

Question

我想更新我的數據庫，使用MySQL PHP的PDO更新語句。然而，它返回我的錯誤：

SQLSTATE [HY093]：無效的參數編號：綁定變量的數量不匹配令牌數

有人能告訴我，我要去哪裏錯了？

我的代碼是：

$sqlupd = "UPDATE 'vendorprof' 
    SET 'vd_loc_add1' = :Add1, 
    'vd_loc_add2' = :Add2, 
    'vd_loc_city' = :City, 
    'vd_loc_state' = :State, 
    'vd_cont_per' = :ContPerson, 
    'vd_cont_mob' = :Mobile, 
    WHERE 'vd_user_id' = :userid2"; 

$profileupd = $conn->prepare($sqlupd); 
$profileupd->bindParam(":Add1",$Add1); 
$profileupd->bindParam(":Add2",$Add2); 
$profileupd->bindParam(":City",$City); 
$profileupd->bindParam(":State",$State); 
$profileupd->bindParam(":ContPerson",$ContPerson); 
$profileupd->bindParam(":Mobile",$Mobile); 

$profileupd->execute(); 
echo $profileupd->rowCount()."records updated Successfully";

顯然，你聲明7個參數標記，但只有6你是1個參數標記綁定短。

:Add1 // is bound as $Add1 
:Add2 // is bound as $Add2 
:City // is bound as $City 
:State // is bound as $State 
:ContPerson // is bound as $ContPerson 
:Mobile // is bound as $Mobile 
:userid2 // is bound ... not 

此外，您的查詢是錯誤的。您不要用引號包住列名。另外，您確實在WHERE之前放置了一個逗號......它必須是：

$sqlupd = "UPDATE vendorprof 
    SET vd_loc_add1 = :Add1, 
    vd_loc_add2 = :Add2, 
    vd_loc_city = :City, 
    vd_loc_state = :State, 
    vd_cont_per = :ContPerson, 
    vd_cont_mob = :Mobile 
    WHERE vd_user_id = :userid2";
