CodeSOD: The Bare Minimum

Let's say you needed to find the maximum and minimum values for a field in a SQL database. If you're like most people, you might write a query like SELECT MAX(someval), MIN(someval) FROM table.

That's the least you could do. That's the bare minimum. And do you want to be the kind of person who does the bare minimum? Kevin L's co-worker doesn't. He's a Brian.

 $querymin = " select hmid "; $querymin .= " from tagdetail "; $querymin .= " Where tagdetail.tag_ordr_ref=$grphdr_tag_ordr_ref"; $querymin .= " and tagdetail.refgrp=$grphdr_refgrp "; $querymin .= " order by hmid "; $resultmin = displayTable($conn_id1, $querymin, "N", ""); $counter = 1; foreach ($resultmin as $a) { $count_rcds = $count_rcds + 1; if ($counter == 1) { $min_hmid = (trim($a [hmid])); } $max_hmid = (trim($a [hmid])); $counter = $counter + 1; }

That's way better than using aggregate functions.
