Answer 1

well my query running successfully just the quesion was that i wanted to bring some changes in the query to retrieve the complete record which has no transaction in sales
for exmple
if i write the quey
select dept.deptno,sum(sal) from emp,dept
where dept.deptno = emp.deptno
group by dept.deptno
the recult comes as
DEPTNO SUM(SAL)
10 8750
20 10875
30 9400
though there is another deptno which is deptno no 40
have no sal
and when i use this query
select dept.deptno,sum(sal) from emp,dept
where dept.deptno = emp.deptno(+)
group by dept.deptno
it shows the dept no 40 also
DEPTNO SUM(SAL)
10 8750
20 10875
30 9400
40
so to get this i posted query which was to long to understand easily.
i accept that i sholud post short query to make other understand
so check out this
select STOCK_rEG.item_code AS ITEM_CODE,SUM(qty) as qty
FROM
SALES_DETAILR,SALES_HEADERR,STOCK_REG
WHERE SALES_DETAILR.SR_ID = SALES_HEADERR.SR_ID AND
SALES_DETAILR.STOCKCODE = STOCK_REG.STOCKCODE
AND RETURN_DATE = '01-APR-08'
GROUP BY STOCK_rEG.item_code
ORDER BY TO_NUMBER(ITEM_CODE) ASC
when i execute this query i get the following result
ITEM_CODE QTY
84 2
102 3
108 3
116 6
166 3
170 3
thoug there is other items are aalso available in stock which transaction
yet not been done or not been sold out/
so when i use the outer join i get the same result
select STOCK_rEG.item_code AS ITEM_CODE,SUM(qty) as qty
FROM
SALES_DETAILR,SALES_HEADERR,STOCK_REG
WHERE SALES_DETAILR.SR_ID = SALES_HEADERR.SR_ID AND
SALES_DETAILR.STOCKCODE(+) = STOCK_REG.STOCKCODE
AND RETURN_DATE = '01-APR-08'
GROUP BY STOCK_rEG.item_code
ORDER BY TO_NUMBER(ITEM_CODE) ASC
ITEM_CODE QTY
84 2
102 3
108 3
116 6
166 3
170 3
hope i tried to make u understand on better way
