How to use GROUP BY in this Query

Question

The below query has TRUNC funtion and I don't want the NMR field to put in group by, but it should be in select.
Please help
SELECT H.SAM_ATTUID AS ATTUID1,
B.AGENT_ID,
TRUNC (NVL (FORC_ANNREV_PAID, CALC_ANNREV_PAID) / 12, 2) AS NMR,
PRODUCT_GROUP
FROM CNT380_TRAN_DATA A,
CNT350_INWARD_DATA B,
CNT330_CODE_VALUE C,
CNT460_COMM_DATA D,
CNT100_PROD_CUST E,
CNT120_AGENT F,
CNT127_AGENT_CAM G,
CNT470_SAM H,
CNT481_MSA_SAM K
WHERE A.INWD_REF_NBR = B.INWD_REF_NBR
AND A.INWD_REF_NBR = A.REF_NBR
AND A.INWD_REF_NBR = D.INWD_REF_NBR
AND A.CYCLE_DATE >= '01-SEP-08'
AND A.CYCLE_DATE <= '30-SEP-08'
AND B.SUBSID_CD = 'EAST'
AND INWD_AGENT_CHAN = 'EALI'
AND (NVL(FORC_ANNREV_PAID,CALC_ANNREV_PAID) <> 0
OR NVL(FORC_ANNREV_RECOUP,CALC_ANNREV_RECOUP) 0)
AND (B.PROD_CLASS_CD 'MSGWK' OR B.PROD_CLASS_CD IS NULL)
AND RTRIM(B.ALTERNATE_PROD_CD) = RTRIM(C.CD_VALUE (+) )
AND RTRIM(A.SPECIAL_PROCESS_IND) IN
'ADD'
,'NEW'
,'WB'
AND A.ACTIVITY_IND = 'I'
AND B.AGENT_ID = G.AGENT_ID (+)
AND B.SUBSID_CD = G.SUBSID_CD (+)
AND A.SO_CMPL_DATE >= G.START_EFF_DATE
AND (A.SO_CMPL_DATE <= G.END_EFF_DATE OR G.END_EFF_DATE IS NULL)
AND (H.SAM_ATTUID <> 'DUMMY' AND H.SAM_ATTUID IS NOT NULL)
AND H.SAM_CD=K.SAM_CD
AND H.SUBSID_CD=K.SUBSID_CD
group by
b.AGENT_ID,
PRODUCT_GROUP,
SAM_ATTUID

Answer 1

You have two choice
1. Use an aggregate function like MIN, MAX etc on FORC_ANNREV_PAID, CALC_ANNREV_PAID
2. Include FORC_ANNREV_PAID, CALC_ANNREV_PAID in the group by.
