How to combine 2 queries into one datastore
 
I have this script in /cron that will query the database and update the datastore
Code:
<?php

if (!is_object($vbulletin->db)) {
        exit;
} else {
        $db = &$vbulletin->db;
}

$totalapps    = 0;
$programstats = array();

$appresult = $db->query_read("
        SELECT programid
            , COUNT(*) AS apps
          FROM " . TABLE_PREFIX . "application
        GROUP
            BY programid
");

while ($program = $db->fetch_array($appresult)) {
        $totalapps += $program['apps'];
        $programstats[$program['programid']] = $program['apps'];
}

build_datastore(
        'appstats',
        serialize(array('total' => $totalapps, 'programs' => $programstats)),
        true
);
I'd like to extend the query and datastore a bit by adding another query
Code:
$avgtime = $db->query_read("
        SELECT programid,
        ceil(avg((resultdate-datesubmitted)/86400)) as average
          FROM application
        where finalresult ="Admit" OR
              finalresult ="Reject" AND
              resultdate > 0
              group by programid
");
Would anyone kindly advise me on how to put this extra query in the existing script and update the datastore so I can call the extra variables?

Thanks a lot

Hey, still playing catch up on the emails. :(

This should do it:
PHP Code:
<?php

if (!is_object($vbulletin->db)) {
        exit;
} else {
        $db = &$vbulletin->db;
}

$totalapps    = 0;
$averages     = array();
$programstats = array();

$appresult = $db->query_read("
        SELECT programid
             , COUNT(*) AS apps
          FROM " . TABLE_PREFIX . "application
        GROUP
            BY programid
");

while ($program = $db->fetch_array($appresult)) {
        $totalapps += $program['apps'];
        $programstats[$program['programid']] = $program['apps'];
}

$avgtime = $db->query_read("
        SELECT programid,
        ceil(avg((resultdate-datesubmitted)/86400)) as average
          FROM application
         where finalresult ="Admit" OR
               finalresult ="Reject" AND
               resultdate > 0
               group by programid
");

while ($program = $db->fetch_array($avgtime)) {
    $averages[$program['programid']] = $program['average'];
}

build_datastore(
        'appstats',
        serialize(array('total' => $totalapps, 'programs' => $programstats, 'averages' => $averages)),
        true
);
Cheers
