retrieve more than one columns using declared-sql

[catherinelo]

I am using JBoss 4.0.1SP1 and mysql

I have this JBoss declared-sql :
SELECT c.Status, Month(c.firstUsed), COUNT(c.serialNumber) FROM Card c WHERE c.status = 4 GROUP BY Month(c.firstUsed)

here is my jbosscmp-jdbc.xml:

<query-method>
<method-name>ejbSelectCountCardsUsed</method-name>
<method-params>
</method-params>
</query-method>

<declared-sql>
< select >
<ejb-name><![CDATA[Card]]></ejb-name>
<field-name><![CDATA[status]]></field-name>
< alias ><![CDATA[c]]>< /alias >
<additional-columns><![CDATA[, Month(c.firstUsed), COUNT(c.serialNumber)]]></additional-columns>
< /select >
< where ><![CDATA[ c.status = 4 GROUP BY Month(c.firstUsed)]]>< /where >
</declared-sql>

Is there anyway I can read these Month(c.firstUsed), COUNT(c.serialNumber) from the collection returned by this query?
