rowCount() 方法試過好像沒用；下面這個方法也沒用$sql = "SELECT COUNT(*) FROM folks";if ($STH = $DBH->query($sql)) { # check the row count if ($STH->fetchColumn() > 0) { # issue a real select here, because there's data! } else { echo "No rows matched the query."; }}

//$rs->exec();
$rs->execute();
$num = $rs->rowCount();
if（$num）{
