使用PDO创建表-不起作用

Question

I know there are a few threads on this, but I've gone through them and haven't yet found a solution.

The problem I'm having is that when I execute my code to create a table using PHP's PDO object, nothing happens. I don't get an error, but I don't get a table either.

Here is my code:

    $pdo = new pdo('mysql:localhost;ijdb','root','');
try {  
    $sql = 'CREATE TABLE joke 
    (
            id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
            joketext TEXT,
            jokedate DATE NOT NULL
    ) DEFAULT CHARACTER SET utf8 ENGINE=InnoDB'; 
    $pdo->exec($sql);
    $sql = 'INSERT INTO joke values
    (
        (1,"jokes","2014-04-22")
    )';
    $pdo->exec($sql);
 } 
catch (PDOException $e) {  $output = 'Error creating joke table: ' . $e->getMessage();
exit(); }

As I said, nothing happens at all, the table isn't created.

Any help would be greatly appreciated! And if this is a duplicate post, please point me in the right direction and I'll remove this post.

If you want to make this work, do the following:

Sidenote: This will create a new data entry of the same jokes and 2014-04-22 .

If you don't want to keep adding the same, set a new query along with a seperate script using
(PDO with) prepared statements . and/or set your columns to be UNIQUE .

Nota: The 1 should be omitted from the INSERT , since your id column is AUTO_INCREMENT .

try {

 $pdo = new pdo('mysql:host=localhost;dbname=your_db', 'username', 'password_if_any');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "CREATE TABLE IF NOT EXISTS joke
    (
            id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
            joketext TEXT,
            jokedate DATE NOT NULL

                ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

    INSERT INTO joke (joketext, jokedate) values ('jokes','2014-04-22')";

    $pdo->exec($sql);

 } 
catch (PDOException $e) {  

$output = 'Error creating joke table: ' . $e->getMessage();

echo $output;
exit(); 
}
