用PDO创建表

Question

I get this error:

Uncaught Error: Call to undefined method PDO::execute()

My code:

<?php
session_start();
require("../connecting-to-database.php");

$query = "CREATE TABLE `classes`(
                       `ID_class` int(11),
                       `name` varchar(255),
                       PRIMARY KEY(`ID_class`))";
$pdo->execute($query);

What is my problem?

Answer 1

Execute is for prepared statements not executing directly.
Also don't forget to catch your exception.

Try the following:

<?php
session_start();
require("../connecting-to-database.php");


try {
$query = $pdo->prepare("CREATE TABLE `classes`(
                   `ID_class` int(11),
                   `name` varchar(255),
                   PRIMARY KEY(`ID_class`))");
$query->execute();
}
catch (PDOException $e) {
  echo $e->getMessage();
}
