Hi,
here is the query
SELECT rs.id AS sid, rs.name AS sname, rc.id AS campid, rc.name AS campname, rc.rev_type AS revtype, rc.act_type
AS actntype, ra.id AS advid, ra.name AS advname, rpt_chn.id AS chanid, rpt_chn.name AS channame, rpt_cre.dn AS dn, SUM(rm.imdel) AS impression, SUM(rm.cdel) AS click,
rd.sqldate AS date FROM rm, rn CROSS JOIN rd, ra, rs, rc, rpt_chn, rpt_cre WHERE rm.date_key = rd.key AND rm.net_key = rn.key AND rm.adv_key = ra.key AND rm.camp_key = rc.key AND rm.s_key = rs.key AND rm.chn_key = rpt_chn.key AND
rm.cre_key = rpt_cre.key AND ra.name != 'SYSTEM' AND rd.sqldate BETWEEN '12/1/2006' AND '12/30/2006' AND ( rn.id IN ( 607 ) ) GROUP BY rd.sqldate
, rs.id, rs.name, ra.id, ra.name, rc.id, rc.name, rc.rev_type
, rc.act_type, rpt_chn.id, rpt_chn.name, rpt_cre.dn;
