Bug in db query->count?

[Trioxin]

How can I do multiple conditions like this using AND? Looking at the docs here (https://userspice.com/documentation-db-class-2/) I tried using db-query once again...
$poolQ = $db->query("SELECT * FROM pools WHERE id = ?",$poolID);
$poolO = $poolQ->results();
print_r($poolO);

and once again what I got was results from the

Code:

users

table even though my query specified the

Code:

pools

table. I'm not sure how I should setup an AND with db->get. Also, you said passing my input as an array rather than how I did in the example in this post will clean the variable from injection?

Thanks
