     <statement id="0" type="select">
          SELECT 'Service Code','MSISDN','Timestamp' from dual
     </statement>
     <statement id= "1" type="select">
          SELECT m.CAMPAIGN, c.MSISDN, c.EVENT_TIME, c.EVENT
          FROM CAMA.CDR_EVENT c, CAMA.MESSAGES m, CAMA.PARTNERS p
          where m.ID = c.MSG_ID   and p.ID = m.PARTNER_ID   and p.ID = @{{PARTNER_ID}}
          and c.EVENT_TIME <= to_timestamp('@{{MIN_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
          and c.EVENT_TIME >  to_timestamp('@{{MAX_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
     </statement>
</DBOFlatSelect>

will generate the output:
