SQL Update table (Azure with PHP) - php

Question

somehow i must make a mistake somewhere and can't seem to find the correct solution, must be doing something wrong. I want to update my Azure SQL table called Celebrity from a PHP page and it doesn't update. Can you pls help me or tell me what i am doing wrong
<?php
try {
$conn = new PDO( "sqlsrv:Server= $host ; Database = $db ", $user, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch(Exception $e){
die(var_dump($e));
}
if(!empty($_POST)) {
try {
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
$id = $_POST['id_celebrity'];
$sql_update = "UPDATE
Celebrity
SET
(FirstName, LastName)
VALUES
(?,?)
WHERE
id_celebrity='$id'";
$stmt = $conn->prepare($sql_update);
$stmt->bindValue(1, $FirstName);
$stmt->bindValue(2, $LastName);
$stmt->execute();
}
catch(Exception $e) {
die(var_dump($e));
}
echo "Celebrity Updated in DB!";
}
?>
Here is the instruction in use and this is what i get back from the AZURE server:
object(PDOException)#3 (8) { ["message":protected]=> string(97) "SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '('." ["string":"Exception":private]=> string(0) "" ["code":protected]=> string(5) "42000" ["file":protected]=> string(62) "D:\home\site\wwwroot\CelebrityOverview\CelebrityEditResult.php" ["line":protected]=> int(57) ["trace":"Exception":private]=> array(1) { [0]=> array(6) { ["file"]=> string(62) "D:\home\site\wwwroot\CelebrityOverview\CelebrityEditResult.php" ["line"]=> int(57) ["function"]=> string(7) "execute" ["class"]=> string(12) "PDOStatement" ["type"]=> string(2) "->" ["args"]=> array(0) { } } } ["previous":"Exception":private]=> NULL ["errorInfo"]=> array(3) { [0]=> string(5) "42000" [1]=> int(102) [2]=> string(80) "[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '('." } }

Answer 1

Try this instead:
$sql_update = "UPDATE Celebrity
SET FirstName = ?, LastName = ?
WHERE id_celebrity='$id'";
Assigning each column a value with a comma in between, UPDATE markup is not same as INSERT.
