Can you explain how JOINs work?
I think I understand the syntax of this, but how does this store in $sQry? Is this a 2D array? In other words, how do I access each value? Sorry, this is probably a stupid question. Also, did you memorize how to write this off the top of your head?
$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';
EDIT: I tried this in my own project and I get the error:
Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\Simpolls\user.php on line 37
I have tables: users, polls, and choices. Polls contains userid, and choices contains pollid. I'm trying to get all polls with userid $currentid and then join those results with the choices for each poll (pollid). 'date' is a timestamp value in my polls table, if that sounds right. Hmm...
$result = mysql_query('SELECT *
FROM polls p WHERE p.userid = "' . $currentid . '"
INNER JOIN choices c ON c.pollid = p.pollid
ORDER BY p.date DESC', $connection);
while($row = mysql_fetch_array($result))
