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.
