yii删除所有查询缓存

Question

I am using Yii 1.14 on centos 5 with php 5.2.4. I am doing query caching like Projects::model()->cache(timeout,dependancy)->findAll(array()). Now I have many of these. is there a way to clear all the query cache of this application. i cannot seem to find any info of adding these cache queries to a group and then delete the group from the cache. The problem is i have many applications using memcache and i do not want to flush it every time before a update. I only want to clear all cache related to this application.

Updated I would like to flush the app cache on the beginning and end of update. i have no file beginning with cache in that location

 ll paradox/protected/runtime/
total 164
-rw-r--r-- 1 apache apache 155571 Jun  3 15:53 application.log
drwxr-xr-x 2 apache apache   4096 Jun  4 11:53 gii-1.1.12
drwxr-xr-x 2 apache apache   4096 Jun  4 11:53 gii-1.1.14

Looking at the logs the Yii::app()->cache->flush does following

<28 new auto-negotiating client connection
28: Client using the ascii protocol
<28 get ns9e5np1ss92i7mqkjues577o1
>28 sending key ns9e5np1ss92i7mqkjues577o1
>28 END
<39 version
>39 VERSION 1.4.5
<39 flush_all
>39 OK

That looks like it clears all the memcache?

if you need it after update s/ redeploy an option is to manually deleting the file:
/protected/runtime/cache-1.1.xx.db
