MySQL & php PDO how to fetch: SELECT EXISTS (SELECT 1 FROM x WHERE y = :value) -


i'm using syntax instead of count (*) because it's supposed faster dont know how fetch resulting output

$alreadymember = $database->prepare('select exists ( select 1  thecommunityreachlinkingtable  communitykey = :communitykey  , userid = :userid)'); $alreadymember->bindparam(':communitykey', $_post['communitykey'], pdo::param_str); $alreadymember->bindparam(':userid', $_post['userid'], pdo::param_int); $alreadymember->execute();  if($alreadymember->fetch()) {do code here}

but doesn't seems return correct, idea?

the use of exists seems wrong here. execute query instead:

select 1  thecommunityreachlinkingtable  communitykey = :communitykey  , userid = :userid
