使用PDO MySQL插入2个表

Question

可能重复:
MySQL插入多个表？(数据库规范化？)

我试图使用PDO将我的记录插入2个表,我有以下内容

try {
  // Connect and create the PDO object
 $conn = new PDO("mysql:host=$hostdb; dbname=$namedb", $userdb, $passdb);
$conn->exec("SET CHARACTER SET utf8");      // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

 $sql = "INSERT INTO `directory` (`First_Name`,`Surname`,`Nicknames`) 
      VALUES (:firstname, :surname, :nicknames) ";

 $statement = $conn->prepare($sql);
 $statement->bindValue(":firstname", $firstname);
 $statement->bindValue(":surname", $surname);
 $statement->bindValue(":nicknames", $nicknames);


 $count = $statement->execute();

  $conn = null;        // Disconnect
}
catch(PDOException $e) {
  echo $e->getMessage();
}

将我的数据插入1表中,如果我使用(我认为是什么),但是我的页面没有呈现并且没有输出源代码？任何人都可以看到我在哪里出错了吗？

try {
  // Connect and create the PDO object
 $conn = new PDO("mysql:host=$hostdb; dbname=$namedb", $userdb, $passdb);
$conn->exec("SET CHARACTER SET utf8");      // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

 $sql = "INSERT INTO `directory`, `nicknames`  (`First_Name`,`Surname`,`Nicknames`) 
      VALUES (:firstname, :surname, :nicknames) ";

 $statement = $conn->prepare($sql);
 $statement->bindValue(":firstname", $firstname);
 $statement->bindValue(":surname", $surname);
 $statement->bindValue(":nicknames", $nicknames);


 $count = $statement->execute();

  $conn = null;        // Disconnect
}
catch(PDOException $e) {
  echo $e->getMessage();
}

这不是有效的SQL; 你需要分开做.也许:

$sql = "
    INSERT INTO `directory`(`First_Name`,`Surname`,`Nicknames`) VALUES (:firstname, :surname, :nicknames);
    INSERT INTO `nicknames`(`First_Name`,`Surname`,`Nicknames`) VALUES (:firstname, :surname, :nicknames);
";
