Here's something I just did along these lines the other day for the Single 
Sign-On module I just contributed to Drupal.  (Note that Drupal's 
db_query() function takes the SQL string as the first parameter and an 
unlimited number of parameter values as subsequent parameters.)

$in   = substr(str_repeat("'%s',", count($sids)), 0, -1);
$sql  = "UPDATE sessions SET uid = %d WHERE sid IN ($in)";
$args = array_merge(array($sql), array($user->uid), $sids);

call_user_func_array('db_query', $args);
