PDO query is not working - php

Question

I am trying to run a simple SELECT query. here is the query
$sql1=$conn->prepare("SELECT q.quoteid, q.customername, q.customersurname, q.timestamp, o.name
FROM quotes as q, occasions as o
WHERE q.occasionid=o.occasionid
AND companyid=1
AND q.day=:day
AND q.month=:month
AND q.year=:year
AND staffid='-1'
AND (q.complete != 'W' OR q.complete != 'Y')
AND q.online=0");
$sql1->execute($exearray);
/* here $exearray contain following value */
Array ( [:day] => 24 [:month] => 1 [:year] => 2014 )
Its not even showing any error.
If I pass static value 1 in month it is showing data.
I run this query directly on DB its working.
So I think there is no error in query.
I am running this query locally on MAMP.

Answer 1

have you tried to parse your month's data to string before passing to the pdo???
$exearray = array(':day'=>24, ':month'=>(string)1, ':year'=>2014);
once i faced this situation and i did this and it worked for me.
i always have this problem while i trying to use LIMIT command in mysql. i just parse my value to string or pass it through statically.
and it doesn't relevant to your MAMP. i have this problem on LAMP and WAMP too.
apparently it's a common problem which it's in PDO libraries.
and for the record don't forget to use intval() while you pass your month's variable directly to your query.

You need to fetch your result, execute only returns a boolean (true or false) whether query execution succeeded or not.
Example:
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll();
print_r($result);

Perhaps doing it the "long-way" with the parameters, and/or changing the query to use a join would help.
Also, the try/catch on PDOException might provide more information.
Lastly, note the $cmd->fetch(PDO::FETCH_ASSOC) invoked for iterating through the recordset.
try {
$db = new PDO("mysql:host=localhost;charset=utf8", "root", "root");
$cmd = $db->prepare("
SELECT q.quoteid, q.customername, q.customersurname,
q.timestamp, o.name
FROM quotes q
LEFT JOIN occasions o on q.occasionid = o.occasionid
WHERE companyid=1
AND q.day = :day
AND q.month = :month
AND q.year = :year
AND staffid = '-1'
AND (q.complete != 'W' OR q.complete != 'Y')
AND q.online = 0
");
$cmd->bindParam(':day', 24, PDO::PARAM_INT);
$cmd->bindParam(':month', 1, PDO::PARAM_INT);
$cmd->bindParam(':year', 2014, PDO::PARAM_INT);
if ($cmd->execute()) {
while ($row = $cmd->fetch(PDO::FETCH_ASSOC)) {
echo $row['quoteid']."|".$row['customername']."|".$row['name']."<br/>";
}
} else {
echo "$cmd->execute() returned false.";
}
} catch (PDOException $e) { echo $e->getMessage(); return; }

In table month column type was Varchar.
I change that to integer and now it is working.
p.s. I have tried using (string) before variable and even double quotes and single quotes on variable value but it didn't work.
Thank you everyone. :)
