问题描述
我有这个完全相同的代码在另一台服务器上运行良好:
I have this exact same code working great on another server:
$mysqli_Cxn = new mysqli($SQL_HOST,$SQL_USER,$SQL_PASS,$SQL_DB);
if($mysqli_Cxn->connect_errno){
echo 'Unable to connect!!';
exit();
}
$userID=12345;
$userFirstName = 'Charley';
$userLocale = 'en_US';
$sql = "UPDATE userProfile SET userFirstName=?, userLocale=? WHERE id=?";
if($stmt = $mysqli_Cxn->prepare($sql)){
if(!$stmt->bind_param('ssi',$userFirstName,$userLocale,$userID)){
echo "<br/><br/>Binding parameters failed: (" . $stmt->errno . ") " . $stmt->error;
}
if($stmt->execute()){
totalAffected=$stmt->affected_rows;
if($totalAffected>=1){
echo '<br/><br/>UPDATE OK: Affected rows = '. $totalAffected;
}
}else{
echo "Execute failed: (" . $stmt->errno . ") " . $stmt->error;
}
}
$stmt->close();
该代码给了我以下输出:执行失败:(1210) mysql_stmt_execute 的参数不正确
That code gives me the following output:Execute failed: (1210) Incorrect arguments to mysql_stmt_execute
如果我改变这两行:
$sql = "UPDATE userProfile SET userFirstName=?, userLocale=? WHERE id=?";
$stmt->bind_param('ssi',$userFirstName,$userLocale,$userID);
为此:
$sql = "UPDATE userProfile SET userFirstName=?, userLocale='en_US' WHERE id=12345";
$stmt->bind_param('s',$userFirstName);
...然后更新成功,我没有收到任何错误.
...then the Update is successful and I don't get any error.
有谁知道为什么我不能在这段代码中绑定多个参数?
我让这段代码在 Centos 4.9、PHP 5.3.3、MySQL 5.0.91/5.0.91-community-log 上完美运行
I had this code running perfectly on a Centos 4.9, PHP 5.3.3, MySQL 5.0.91/5.0.91-community-log
我需要在我当前的服务器上运行它,它是 Centos 6.2、PHP 5.3.10、MySQL 5.0.95-community-log
I need to run it on my current server which is Centos 6.2, PHP 5.3.10, MySQL 5.0.95-community-log
推荐答案
我做了一点研究,结合您的 GCC 版本和您使用的优化标志,这似乎是 MySQL 源中报告的错误.如果您无法更改 MySQL 版本,请尝试重新编译 MySQL,并将 -fno-strict-aliasing 添加到您的 CFLAGS.
I did a little research, and it seems like a reported error in the MySQL source in combination with your version of GCC and the optimization flags you use.If you can't change the MySQL version, try recompile MySQL with added -fno-strict-aliasing to your CFLAGS.
