MySQL vérifie si la table existe déjà

Pas besoin de requête. lancez simplement ceci

$this->db->table_exists('customer');

Données du tableau

Exemple

$query = $this->db->table_exists('customer');
$count = count($query);

if (empty($count)) {
    echo "No Table Found";
}
elseif ($count == 1) {
    echo "Oopzz! There is table";
}
elseif ($count >1) {
    echo "Ohh !! There are many tables";
}
