Date Parameter : Unable to retrieve data thru data template

Question

I have a data template with a date parameter. I used it in a query to extract records for a specific date. No matter which format I use in the query, the query returns a null although there are records. Please advise. I need this as soon as possible.
<parameter name="PD" dataType="date" />SELECT to_char(run_date,'DD-MON-YYYY') C_RUN_DATE ,cust_action ACTION,count(1) ACTION_COUNT from CDL hdrlog where
last_run_status='A' and to_char(run_date,'DD-MON-YYYY') = :PD group by to_char(run_date,'DD-MON-YYYY'),cust_action
order by c_run_date
I tried with to_char, to_date etc... nothing works.
thanks

See example below for date,note the format we supported as state in the doc.
If you would like to set as character then change type to character and use to_char around the bind var.
<?xml version="1.0" encoding="WINDOWS-1252" ?>
<dataTemplate name="dataTemplateName" description="Template description" version="1.0">
<parameters>
<parameter name="p_hiredate" dataType="date">1980-12-17</parameter>
</parameters>
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[SELECT d.DEPTNO,d.DNAME,d.LOC,
                     EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,nvl(COMM,0) from dept d, emp e
                      where hiredate=:p_hiredate]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_DEPT" source="Q1">
<element name="DEPT_NUMBER" value="DEPTNO" />
<element name="DEPT_NAME" value="DNAME"/>
<element name="DEPTSAL" value="G_EMP.SALARY" function="SUM()"/>
<element name="LOCATION" value="LOC" />
<group name="G_EMP" source="Q1">
<element name="EMPLOYEE_NUMBER" value="EMPNO" />
<element name="NAME" value="ENAME"/>
<element name="JOB" value="JOB" />
<element name="MANAGER" value="MGR"/>
<element name= "HIREDATE" value="HIREDATE"/>
<element name="SALARY" value="SAL"/>
</group>     
</group>
</dataStructure>
</dataTemplate>
