O/H Chris Curvey ??????:
It's quite possible that I'm missing something obvious here. The
following code fragment does not return any rows, but if I take out
the parameters and replace them with hardcoded strings (enclosed in
single quotes), I get the right results.
I've scattered "print" statements throughout, and the query seems to
get past execute() OK, it's just not returning anything from the call
to fetch()
Am I missing something obvious?
$stmt = $conn->prepare("select t.z from towns t
join counties c on t.county_z = c.z
where t.me = ?
and c.state_z = ?");
if ($stmt->execute($parts)) {
while ($row = $stmt->fetch()) {
$town_z = $row['z'];
}
What is $parts doing ?? You just need execute() and I suppose although
not posted that you did construct the object like:
$conn| = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
|A good choice is to tell fetch a way to retrieve your data like this:
$town_z = $stmt->fetch(PDO::FETCH_ASSOC);
although I think that it will get both result sets in case you don't define.
} else {
print $stmt->errorCode();
print_r($stmt->errorInfo());
}
Thanks in advance!
A better way debug that I know is using exceptions like:
try {
$sth = $conn->query($query);
$rs = $sth->fetch();
} catch (Exception $e) {
print "failed :".$e->getMessage();
}
You can use try {} with almost everything so give it a "try" :-) .
Send us some feed back or post full source if you keep having trouble.
