Hi, My current query is something like: $_names = qq[select NAMES from ADDRESS where ID='$id' and area='$area' ]; $names_ = $dbh->prepare($_names); $names_->execute;" I want to remove that $id and $area directly and use ? placeholders.. How do I do it ? is it $_names=qq[selct .. id=? and area=? , $undef, $id, $area ] ?
