Follow below steps:
Step1: Agreegate data based on "Date", fetch Min and Max of
Weight.
date MAX(Weight) Min(Weight)
1-Jan-14 5 2
2-Jan-14 5 2
Step2: Join with the source data using Date
seq_no date bill_amt weight MAX(Weight)
Min(Weight)
11 1-Jan-14 100 2 5 2
14 1-Jan-14 98 2 5 2
15 1-Jan-14 105 3 5 2
16 1-Jan-14 11 3 5 2
12 1-Jan-14 40 5 5 2
13 1-Jan-14 32 5 5 2
11 2-Jan-14 40 2 5 2
14 2-Jan-14 198 2 5 2
15 2-Jan-14 15 3 5 2
16 2-Jan-14 16 3 5 2
12 2-Jan-14 100 5 5 2
13 2-Jan-14 132 5 5 2
3. Using expression, create 2 flags.
a, Flag1 - iif(Weight=min(weight),Bill_amt,NULL)
b, Flag2 - iif(Weight=max(weight),Bill_amt,NULL)
seq_no date bill_amt weight MAX(Weight)
Min(Weight) Flag1 - iif(Weight=min
(weight),Bill_amt,NULL) Flag2 - iif(Weight=max
(weight),Bill_amt,NULL)
11 1-Jan-14 100 2 5 2 100
14 1-Jan-14 98 2 5 2 98
15 1-Jan-14 105 3 5 2
16 1-Jan-14 11 3 5 2
12 1-Jan-14 40 5 5 2
40
13 1-Jan-14 32 5 5 2
32
11 2-Jan-14 40 2 5 2 40
14 2-Jan-14 198 2 5 2 198
15 2-Jan-14 15 3 5 2
16 2-Jan-14 16 3 5 2
12 2-Jan-14 100 5 5 2
100
13 2-Jan-14 132 5 5 2
132
4.Agregate Max(Flag1) and min (Flag2) group by Date
And you get the Splution,
date Min_Flag_flag Max_flag
1-Jan-14 100 32
2-Jan-14 198 100
