You use joins and let the software structure accordingly.
If you do a query within a loop, it would execute the query for the number of loops. If you had 60 questions, that means you would loop the inner query 60 times which is very expensive.
Pedant's first post there shows the join in question (with the ambiguity of the columns on the join mentioned).
So if I had a questions, and options table (so I could create a radio group for example), that would be similar to so using PHP to format it:
$sQry = 'SELECT q.questionID, q.questionDescription, qo.optionID, qo.option
FROM question q
INNER JOIN questionoption qo ON qo.questionID = q.questionID
ORDER BY q.questionID ASC';
if ($qry = mysql_query($sQry))
$iLast = -1;
if (mysql_num_rows($qry) > 0)
while ($row = mysql_fetch_assoc($qry))
if ($row['questionID'] != $iLast)
// question has changed
if ($iLast > -1)
$iLast = $row['questionID'];
printf('<label for="question_%d">%s</label>', $iLast, $row['questionDescription']);
printf('<select name="question_%d" id="question_%d">', $iLast, $iLast);
printf('<option value="%s">%s</option>', $row['optionID'], $row['option']);
I think I biffed the HTML in there, but that should give you the idea.
