How to do union.

Question

hi all.
i want to create union and view of the following tables.can anyone help me out?I tried without union but counting is comming in wrong result.
thanks in advance.
SELECT PCD_IRS_ID,pcd_plt_id,PLM_PLT_ID,COUNT(pLM_policy_no),
SUM(DECODE(pcd_IRS_id,55,PCD_AMOUNT_LC,0)) TP,
SUM(DECODE(PCD_IRS_ID,56,PCD_AMOUNT_LC,0)) COMPUL
FROM TABLE1,TABLE2
where pcd_plt_id=plm_pLT_id
and pcd_plt_id in('U01','U02')
AND PCD_IRS_ID IN (55,56)
AND trunc(pcd_registry_date)=TRUNC(SYSdate)
AND TRUNC(PLM_REGISTRY_DATE)=TRUNC(SYSDATE)
GROUP BY PLM_PLT_ID,PCD_PLT_ID,PCD_IRS_ID
/ Its counting the policy no in whole tables but i want it count according sysdate.

hi
thanks for reply.
SELECT PCD_IRS_ID,pcd_plt_id,COUNT(pLM_policy_no),
SUM(DECODE(pcd_IRS_id,55,PCD_AMOUNT_LC,0)) TP,
SUM(DECODE(PCD_IRS_ID,56,PCD_AMOUNT_LC,0)) COMPUL
FROM UW_POL_PREM_FEES_DISC_COMMS,UW_POLICY_MASTERS
WHERE pcd_plt_id in('U01','U02')
AND PCD_IRS_ID IN (55,56)
AND trunc(pcd_registry_date)=TRUNC(SYSdate)
AND TRUNC(PLM_REGISTRY_DATE)=TRUNC(SYSDATE)
GROUP BY PLM_PLT_ID,PCD_PLT_ID,PCD_IRS_ID
UNION
SELECT PCD_IRS_ID,pcd_plt_id,COUNT(pLM_policy_no),
SUM(DECODE(pcd_IRS_id,55,PCD_AMOUNT_LC,0)) TP,
SUM(DECODE(PCD_IRS_ID,56,PCD_AMOUNT_LC,0)) COMPUL
FROM UW_POLICY_MASTERS,UW_POL_PREM_FEES_DISC_COMMS
WHERE pcd_plt_id in('U01','U02')
AND PCD_IRS_ID IN (55,56)
AND trunc(pcd_registry_date)=TRUNC(SYSdate)
AND TRUNC(PLM_REGISTRY_DATE)=TRUNC(SYSDATE)
GROUP BY PCD_PLT_ID,PCD_IRS_ID;let me give you separate tables then it will be ok and understandable.
SELECT CBR_ID,PLT_ID,SUM(SUM_PREM),SUM(COUNT_POL)
FROM
SELECT  pcd_cbr_id CBR_ID, pcd_plt_id PLT_ID , sum(pcd_amount_lc) SUM_PREM,0 COUNT_POL
FROM UW_POL_PREM_FEES_DISC_COMMS----------------table1
where trunc(pcd_registry_date)=TRUNC(SYSDATE)
AND PCD_IRS_TYPE!=4
GROUP BY PCD_CBR_ID,PCD_PLT_ID
UNION
SELECT PLM_CBR_ID CBR_ID,PLM_PLT_ID PLT_ID,0 SUM_PREM, COUNT(PLM_POLICY_NO) COUNT_POL
FROM UW_POLICY_MASTERS--------------------------------table2
WHERE  trunc(PLM_registry_date)=TRUNC(SYSDATE)
GROUP BY PLM_CBR_ID,PLM_PLT_ID)
GROUP BY CBR_ID,PLT_ID
ORDER BY CBR_ID,PLT_IDi want the result something like this.
CBR ID   Plt_id        count(policy_no)                                      TP               compul
55-----   U01-----      2----------------------------according sysdate.     $200             00
56-----   u02           5----------------------------according sysdate.     00                $300but my result is comming wrong for Policy counting and its counting the both tables.
here is the result.
PCD_IRS_ID     PCD_PLT_ID     COUNT(PLM_POLICY_NO)     TP     COMPUL
55     u01     115     36390     0 THIS IS WRONG AND ITS COMMING 0(ZERO)
55     U01     5865     1855890     0
55     U01     8855     2802030     0
55     U01     14490     4585140     0
55     U01     29440     9315840     0
55     U02     91     52120     0
55     U02     4641     2658120     0
55     U02     7007     4013240     0
55     U02     11466     6567120     0
55     U02     23296     13342720     0
56     U01     24     0     70110   THIS IS WRONG ITS COMMING MORE AND ITS NOT ACCORDING SYSDATE AND ALSO SAME FOR OTHERS THATS WRONG.
56     U01     1224     0     3575610
56     U01     1848     0     5398470
56     U01     3024     0     8833860

56     U02     1     0     5400
56     U02     51     0     275400
