yii query not caching when using createCommand - caching

Question

I have the following query being logged in mysql which is not being cached.
SELECT
*,
round(priceperkm * IFNULL(KMPlanned, projects.KM),
4) AS NEWVALUE,
round(PRICE * IFNULL(KMPlanned, projects.KM),
2) AS TotalPriceForItem,
SUM(((abs(FSP - LSP) + 1) * SI) / 1000) AS KM_Completed,
round(SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE,
2) AS TotalPrice,
if(round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, projects.KM)) * 100,
2)>100,100,round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, projects.KM)) * 100,
2)) AS TotalPercent
FROM
hdb.projects
join
biditems ON projects.id = biditems.project_id
join
lookupprocess ON biditems.ITEMID = lookupprocess.biditems_id
left join
jobsprocesscomplete ON lookupprocess.ID = lookupprocess_id
left join
detailsseismic ON jobsprocesscomplete.JOBNO = detailsseismic.JOBNO
where
projects.PROJID = '1407075'
and lookupprocess.ID = 16299
The Yii code is as follows.
$dependancy = new CDbCacheDependency("select last_modified_date from projects where PROJID = $projid");
$countJobs = Jobs::model()->cache(CACHE_TIMEOUT,$dependancy)->count(array("condition"=>"PROJID=$projid"));
foreach ($processstages as $k=>$v) {
$sql = "SELECT
*,
round(priceperkm * IFNULL(KMPlanned, projects.KM),
4) AS NEWVALUE,
round(PRICE * IFNULL(KMPlanned, projects.KM),
2) AS TotalPriceForItem,
SUM(((abs(FSP - LSP) + 1) * SI) / 1000) AS KM_Completed,
round(SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE,
2) AS TotalPrice,
if(round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, projects.KM)) * 100,
2)>100,100,round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, projects.KM)) * 100,
2)) AS TotalPercent
FROM
hdb.projects
join
biditems ON projects.id = biditems.project_id
join
lookupprocess ON biditems.ITEMID = lookupprocess.biditems_id
left join
jobsprocesscomplete ON lookupprocess.ID = lookupprocess_id
left join
details".$type['type']." ON jobsprocesscomplete.JOBNO = details".$type['type'].".JOBNO
where
projects.PROJID = :pid
and lookupprocess.ID = :lid
";
$command = Yii::app()->db->cache(CACHE_TIMEOUT,$dependancy)->createCommand($sql); // need to set memecahce to 50m to cache this query
//Yii::log("select last_modified_date from projects where PROJID = $projid",CLogger::LEVEL_INFO, __METHOD__);
$command->bindValue(":lid",$k,PDO::PARAM_INT);
$command->bindValue(":pid",$projid,PDO::PARAM_INT);
Yii::log((memory_get_peak_usage(true))/1024/1024 . "MB",CLogger::LEVEL_INFO, __METHOD__);
$query = $command->query();
}
I cannot seem to figure out why it is not caching these results as the last_modified_date is not changing. i have set max item cache to 32m and memcache memory to 512.
I have rewrote my query to as below which gets cached but the createCommand way it does not
$criteria=new CDbCriteria;
$criteria->select = '
round(priceperkm * IFNULL(KMPlanned, t.KM),
4) AS NEWVALUE,
round(PRICE * IFNULL(KMPlanned, t.KM),
2) AS TotalPriceForItem,
SUM(((abs(FSP - LSP) + 1) * SI) / 1000) AS KM_Completed,
round(SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE,
2) AS TotalPrice,
if(round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, t.KM)) * 100,
2)>100,100,round((SUM(((abs(FSP - LSP) + 1) * SI) / 1000) * PRICE) / (PRICE * IFNULL(KMPlanned, t.KM)) * 100,
2)) AS TotalPercent';
$criteria->join = 'join biditems ON t.id = biditems.project_id ';
$criteria->join .= 'join lookupprocess ON biditems.ITEMID = lookupprocess.biditems_id ';
$criteria->join .= 'left join jobsprocesscomplete ON lookupprocess.ID = lookupprocess_id ';
$criteria->join .= 'left join details'.$type['type'].' ON jobsprocesscomplete.JOBNO = details'.$type['type'].'.JOBNO ';
$criteria->compare('t.PROJID',$projid);
$criteria->compare('lookupprocess.ID',$k);
Projects::model()->cache(CACHE_TIMEOUT,$dependancy)->findAll($criteria);

Answer 1

Try to put the following:
$result = Yii::app()->db->cache(self::CACHE_TIMEOUT,$dependancy)
->createCommand($sql)
->bindValue(":lid",$k,PDO::PARAM_INT);
->bindValue(":pid",$projid,PDO::PARAM_INT)
->findAll();
I assumed that CACHE_TIMEOUT was a constant in this class, but if it is defined in another class, then you need to adapt this part
