To get the amount based on the code

Question

hi all,
i am using db10g.
i have a query like below
SELECT SUM(EID_AMOUNT),EID_INCR_CODE,EIH_EFF_DATE
FROM EMPLOYEE_INC_HEADER,EMPLOYEE_INC_DETAILS
WHERE EIH_EMP_CODE = EID_EMP_CODE
AND EIH_EFF_DATE = EID_EFF_DATE
AND EIH_EMP_CODE = '0026108'
GROUP BY EID_INCR_CODE,EIH_EFF_DATE
ORDER BY EID_INCR_CODE,EIH_EFF_DATEcurrently i am getting result set like this
SUM(EID_AMOUNT) EID_INCR_CODE   EIH_EFF_D
            500 BASIC           01-JAN-09
            750 BASIC           01-MAY-09
            300 HTRAN           01-JAN-09
            500 HTRAN           01-MAY-09
            200 OTHERS          01-JAN-09
            350 OTHERS          01-MAY-09but i want to get the out put like
SUM(EID_AMOUNT) EID_INCR_CODE   EIH_EFF_D
           1250 BASIC           01-JAN-09
            800 HTRAN           01-JAN-09
            550 OTHERS          01-JAN-09in otherwords i want get sum of amount for that incr_code and effective date will be the minimum date amoung which the data is fetched(in the example out of six resulted record '01-jan-09' is the least data).
is there is any way where i can acheive the above?
Please help..

Maybe
select the_sum,
       EID_INCR_CODE,
       EIH_EFF_DATE
  from (SELECT SUM(EID_AMOUNT) over (partition by EID_INCR_CODE order by EIH_EFF_DATE) the_sum,
               EID_INCR_CODE,
               EIH_EFF_DATE,
               row_number() over (partition by EID_INCR_CODE order by EIH_EFF_DATE) rn
          FROM EMPLOYEE_INC_HEADER,
               EMPLOYEE_INC_DETAILS
         WHERE EIH_EMP_CODE = EID_EMP_CODE
           AND EIH_EFF_DATE = EID_EFF_DATE
           AND EIH_EMP_CODE = '0026108'
where rn = 1
ORDER BY EID_INCR_CODE,EIH_EFF_DATEor
SELECT SUM(EID_AMOUNT) KEEP (DENSE_RANK FIRST ORDER BY EIH_EFF_DATE) the_sum,
       EID_INCR_CODE,
       EIH_EFF_DATE
  FROM EMPLOYEE_INC_HEADER,
       EMPLOYEE_INC_DETAILS
WHERE EIH_EMP_CODE = EID_EMP_CODE
   AND EIH_EFF_DATE = EID_EFF_DATE
   AND EIH_EMP_CODE = '0026108'
GROUP BY EID_INCR_CODE,EIH_EFF_DATE
ORDER BY EID_INCR_CODE,EIH_EFF_DATERegards
