What's wrong with my WHERE clause here?

I'm passing $member_id through the function and checking that members.member_id matches $member_id, aren't I? Or maybe not...

function get_member($member_id) {

    try {
      $results = $db->query(
          "SELECT member_id, email, fullname, level
          FROM members
          WHERE members.member_id = $member_id"
    } catch (Exception $e) {
      echo "bad query";

    $members = $results->fetch();
    return $members;

Hi Jacob

If you’re not joining two tables, you don’t need to include the members table name before the field name, so:

members.member_id = $member_id

can become:

member_id = $member_id

It should work in a production environment but sometimes the Treehouse algorithm doesn’t always take that into account!

Good luck and I hope that helps.
