Question

我有关于PDO的问题。这个代码块工作

$MyQuery = $db->prepare("UPDATE project
SET
PeopleId=:PID,
UserId=:UID
WHERE
PeopleId=:PeopleId
AND
UserID=:UserID
AND
(
                alpha = 0
                OR alpha IS NULL
            )  LIMIT ".$Adet);

            $MyQuery->bindParam(":PID", $PID, PDO::PARAM_INT);
            $MyQuery->bindParam(":UID", $UID, PDO::PARAM_INT);
            $MyQuery->bindParam(":PeopleId", $PeopleId, PDO::PARAM_INT);
            $MyQuery->bindParam(":UserID", $UserID, PDO::PARAM_INT);
            $MyQuery->execute();

但它没有用。

$MyQuery = $db->prepare("UPDATE project
SET
PeopleId=:PID,
UserId=:UID
WHERE
PeopleId=:PeopleId
AND
UserID=:UserID
AND
(
                alpha = 0
                OR alpha IS NULL
            )  LIMIT :Count");

            $MyQuery->bindParam(":PID", $PID, PDO::PARAM_INT);
            $MyQuery->bindParam(":UID", $UID, PDO::PARAM_INT);
            $MyQuery->bindParam(":PeopleId", $PeopleId, PDO::PARAM_INT);
            $MyQuery->bindParam(":UserID", $UserID, PDO::PARAM_INT);
            $MyQuery->bindParam(":Count",$Count, PDO::PARAM_INT);
            $MyQuery->execute();

我的错在哪里？我找不到任何东西。我想有一个错误。我将$ Count转换为Integer，但它没有再次运行。任何人都可以帮我解决这个问题吗？

Answer 1

强制$ Count var成为一个整数，

$MyQuery->bindParam(":Count", (int) $Count, PDO::PARAM_INT);

mabye trim :(在Muhammed Almaz tnx评论之后编辑：D）

$Count = trim($Count)    
$MyQuery->bindParam(":Count", (int) $Count, PDO::PARAM_INT);

关于LIMIT的PDO bindParam问题
