Question

I try to count the number of roles in my Drupal database and with the result execute another statement. But for some reason, it’s failing. What do I do wrong?

$numberofroles = db_query('SELECT COUNT(rid) FROM {role}');
$roles = 1;

while ($roles < $numberofroles) {
        db_query('INSERT INTO {taxonomy_access_default} (vid, rid, grant_view, grant_update, grant_delete, grant_create, grant_list) VALUES(0, '.$roles.', 1, 0, 0, 0, 1)');
        $roles++;
}

You forget a? ->fetchField() ?

Drupal6:

$val = db_result(db_query({...}))

Drupal7:

$val = db_query({...})->fetchField();
