PHP/PDO - Flush privileges

Question

I'm doing some mysql server management with a script that flushes the MySQL users privileges when new privileges are added to a MySQL user.

I'm using the PDO class to do my queries, but when I do a simple

FLUSH PRIVILEGES;

I get, for

$connection->exec('FLUSH PRIVILEGES;');

and

$connection->query('FLUSH PRIVILEGES;');

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'mysql.servers' doesn't exist

Is it possible to do such query with the PDO class or do I have to resort to using mysql(i)?

Answer 1

I've just tried the following portion of code :

$dsn = 'mysql:dbname=mysql;host=127.0.0.1';
$user = 'root';
$password = '********';
try {
    $db = new PDO($dsn, $user, $password);
    $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $db->query('flush privileges;');
} catch (PDOException $e) {
    var_dump($e);
}

And I don't get any kind of error like the one you are describing.

Are you sure you don't have some problem with you MySQL server ?

Your error message says that table "mysql.servers" doesn't exists... But when I look at my local MySQL server, there is such a table -- are you sure your installation/configuration is not "broken" and you didn't delete that table or anything like that ?

BTW, it doesn't seem to be some kind of privilege you're not having : if you try to flush privileges without having the required privilege, you get the following error : "SQLSTATE[42000]: Syntax error or access violation: 1227 Access denied; you need the RELOAD privilege for this operation"
