PHP PDO插入数据

我是新的PDO，我试图插入数据到表中。PHP PDO插入数据

这是我的表：

CREATE TABLE `Message` (
`ID` INT(8) NOT NULL AUTO_INCREMENT , 
`DateTime` DATETIME NOT NULL , 
`SmsSid` VARCHAR(34) NOT NULL , 
`AccountSid` VARCHAR(34) NOT NULL , 
`From` VARCHAR(12) NOT NULL , 
`To` VARCHAR(12) NOT NULL , 
`Body` VARCHAR(160) NOT NULL , 
`FromCity` VARCHAR(50) NULL , 
`FromState` VARCHAR(50) NULL , 
`FromZip` VARCHAR(50) NULL , 
`FromCountry` VARCHAR(50) NULL , 
`ToCity` VARCHAR(50) NULL , 
`ToState` VARCHAR(50) NULL , 
`ToZip` VARCHAR(50) NULL , 
`ToCountry` VARCHAR(50) NULL , 
`ConversationNumber` INT(4) NOT NULL , 
PRIMARY KEY ( `ID`) 
) ENGINE = MYISAM

这就是我想要插入到表中的PHP代码。什么是做这个插入语句的正确方法？ prepare（）query（）exec（）？

我能够通过使用这个类似的代码插入到一个不太复杂的表中，但不是上面这个。我不确定究竟是什么导致了问题，语法，列类型，自动增量，日期时间？有没有这张表，我不处理正确的插入查询？另外，我是否正确处理异常/错误处理以查看我需要帮助调试的正确错误消息？

<?php 
try 
{ 
$connectionString = new PDO("mysql:host=xxxx;dbname=xxxx;","xxxx","xxxx"); 
} 
catch(PDOException $e) 
{ 
echo 'Connection failed'.$e->getMessage(); 
} 

$DateTime = "NOW()"; 
$SmsSid = "abcdef"; 
$AccountSid = "abcdef"; 
$FromWho = "abcdef"; 
$To = "abcdef"; 
$Body = "abcdef"; 
$FromCity = "abcdef"; 
$FromState = "abcdef"; 
$FromZip = "abcdef"; 
$FromCountry = "abcdef"; 
$ToCity = "abcdef"; 
$ToState = "abcdef"; 
$ToZip = "abcdef"; 
$ToCountry = "abcdef"; 
$ConversationNumber = "abcdef"; 

try 
{ 
$executeQuery = $connectionString->prepare("INSERT INTO Message (SmsSid,AccountSid,`From`,To,Body,FromCity,FromState,FromZip,FromCountry,ToCity,ToState,ToZip,ToCountry,ConversationNumber) VALUES (:SmsSid,:AccountSid,:FromWho,:To,:Body,:FromCity,:FromState,:FromZip,:FromCountry,:ToCity,:ToState,:ToZip,:ToCountry,:ConversationNumber)"); 

$executeQuery->execute(array(':SmsSid'=>$SmsSid,':AccountSid'=>$AccountSid,':FromWho'=>$FromWho,':To'=>$To,':Body'=>$Body,':FromCity'=>$FromCity,':FromState'=>$FromState,':FromZip'=>$FromZip,':FromCountry'=>$FromCountry,':ToCity'=>$ToCity,':ToState'=>$ToState,':ToZip'=>$ToZip,':ToCountry'=>$ToCountry,':ConversationNumber'=>$ConversationNumber)); 


} 
catch(PDOException $e) 
{ 
echo 'Query failed'.$e->getMessage(); 
} 

$connectionString = null; 
?>

您是否收到任何错误？顺便说一句，我假设所有这些占位符都是变量，为什么你不附加一个$给他们？此外，如果您知道占位符（列字段）的顺序，那么您可以使用问号语法，而不是混乱。 – silkfire 2013-02-24 23:51:47

请不要包含“非常感谢帮助。”在你的问题。这是无用的噪音。 – Doorknob 2013-02-24 23:52:23

@Doorknob在我的回答经验中，很少有人赞赏 – 2013-02-24 23:54:22

From是MySQL中的一个保留字。当你使用它作为一个列的名称，你有反引号包围它作为

`From`

默认情况下，PDO不抛出异常。为了让扔在错误异常，请拨打

$pdoObject->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

这是给我“警告：PDO :: setAttribute（）期待2个参数，1给出” – Jsn0605 2013-02-24 23:58:04

@ Jsn0605对不起，我纠正了错误 – 2013-02-25 00:00:40

谢谢，这有助于一堆，但我仍然无法找到我的语法错误。 “SQLSTATE [42000]：语法错误或访问冲突：1064您的SQL语法错误;查看与您的MySQL服务器版本相对应的手册，以找到正确的语法，以便在”From，To，Body，FromCity，FromState， FromZip，FromCountry，ToCity，ToState，ToZip，ToCount'in line 1“ – Jsn0605 2013-02-25 00:02:37

这是你逃脱（与backticks：`）真正重要的表名和列名也。例如，FROM是MySQL中的保留关键字。

$SmsSid    = "abcdef"; 
$AccountSid   = "abcdef"; 
$From    = "abcdef"; 
$To     = "abcdef"; 
$Body    = "abcdef"; 
$FromCity   = "abcdef"; 
$FromState   = "abcdef"; 
$FromZip   = "abcdef"; 
$FromCountry  = "abcdef"; 
$ToCity    = "abcdef"; 
$ToState   = "abcdef"; 
$ToZip    = "abcdef"; 
$ToCountry   = "abcdef"; 
$ConversationNumber = "abcdef"; 

try { 
    $executeQuery = $connectionString->prepare('INSERT INTO `Message` (`SmsSid`, `AccountSid`, `From`, `To`, `Body`, `FromCity`, `FromState`, `FromZip`, `FromCountry`, `ToCity`, `ToState`, `ToZip`, `ToCountry`, `ConversationNumber`) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)'); 

    $executeQuery->execute(array($SmsSid, $AccountSid, $From, $To, $Body, $FromCity, $FromState, $FromZip, $FromCountry, $ToCity, $ToState, $ToZip, $ToCountry, $ConversationNumber)); 
} 
catch(PDOException $e) { 
     echo 'Query failed' . $e->getMessage(); 
}

尝试使用抽象库的一些动作自动化，如safemysql
你看，你的代码可以大大缩短，而无需多次，重复每个变量的名字 - 最重要的 - 没有必要去关心字段名是否是一个保留字或不 - 所有格式都将自动完成：

<?php 
$db = new safemysql('host'=>'xxxx','db'=>'xxxx','user'=>"xxxx",'pass'=>"xxxx"); 
$insert = array( 
    'SmsSid'    => "abcdef", 
    'AccountSid'   => "abcdef", 
    'From'    => "abcdef", 
    'To'     => "abcdef", 
    'Body'    => "abcdef", 
    'FromCity'   => "abcdef", 
    'FromState'   => "abcdef", 
    'FromZip'   => "abcdef", 
    'FromCountry'  => "abcdef", 
    'ToCity'    => "abcdef", 
    'ToState'   => "abcdef", 
    'ToZip'    => "abcdef", 
    'ToCountry'   => "abcdef", 
    'ConversationNumber' => "abcdef", 
); 
$db->query("INSERT INTO Message SET DateTime = NOW(), ?u", $insert); 
?>

请注意，我直接添加NOW()函数调用到查询，因为它是MySQL函数，不需要格式化。

$sql = "INSERT INTO books2 (title,author,cover) values(?,?,?)"; 

$q = $conn->prepare($sql); 

$q->bindParam(1, $title); 

$q->bindParam(2, $author); 

$q->bindParam(3, $cover, PDO::PARAM_LOB); 

$q->execute();
