Problem in placing sum

Question

I have below result from joinin three tables called TEST table
i placed the below selection in Cursor
ID     Grp     loc     type     Sum_Lower_1     sum_upper_1     Sum_qty_3
101     abc     x     1     50     200     0
101     abc     x     3     0     0     80
102     abc     x     1     100     400     0
102     abc     x     3     0     0     450
103     abc     x     1     500     2000     0
103     abc     x     3     0     0     230
104     abc     x     1     30     120     0
104     abc     x     3     0     0     50the result should find out the id,grp,loc for the followin condn. and we do deletion from an another table for these values
if sum_qty_3 < sum_lower_1 for the particular id,grp,loc
if we take 101,abc,x then 80 < 50 ,so it fails
sum_qty_3 > sum_lower_1 for the particular id,grp,loc
if we take 101,abc,x then 50> 250 ,so it fails
So, the row should not return for this id,grp,loc
finally, we should have the below result
ID     Grp     loc
102     abc     x
103     abc     xif sum_qty_3 < sum_lower_1
delete from product where id = 103 and grp = 'abc' and loc = 'x' and f_type = 2000 if sum_qty_3 > sum_lower_1
delete from product where id = 102 and grp = 'abc' and loc = 'x' and f_type = 1000  how can i achieve this using cursor or any other way
pls help me
thanks in adv

Answer 1

Is this what you are looking for?
select * from test;
O/P
ID     GRP     LOC     TYPE     SUM_LOWER_1     SUM_UPPER_U     SUM_QTY_3
101     abc     x     1     50                                 200         0
101     abc     x     3     0                                     0       80
102     abc     x     1     100                                  400        0
102     abc     x     3     0                                      0     450
103     abc     x     1     500                                 2000     0
103     abc     x     3     0                                       0     230
104     abc     x     1     30                                    120     0
104     abc     x     3     0                                        0     50
SELECT * FROM(
SELECT id, grp, loc, sum(Sum_Lower_1 )sum_l,SUM(Sum_Upper_u) sum_u,SUM(sum_qty_3) qty_3 FROM Test
GROUP BY id,grp,loc)
WHERE sum_l <qty_3 AND sum_u > qty_3 /* you may have to change the greater than condition, i am confused by your data and the o/p you expect
in the original post */
O/P
ID     GRP     LOC     SUM_L     SUM_U     QTY_3
101     abc     x     50     200     80
104     abc     x     30     120     50Cheers!!!
