2, 10, 4.5
1, 30, 5
3, 10, 6
3, 20, 4

1, 9, 3.5, 20
2, 8, 4.5, 20
3, 6, 4, 10

Answer / lakshmi srinivas
source->copy->2 aggregators->join->target
1 aggregator->eno,max(sal),min(sal)
2 aggregator->eno,dno,max(sal)
by using max(sal) key, we can join both o/p of
aggregators,we can get that output...

the question framed wrong
it should have been
empno,dept,sal
1,10,9
1,10,8
1,10,7
2,20,7
2,20,8.5
2,20,9
3,30,4
3,30,6
then expecting an ans is correct
o/p
empno,max(sal),min(sal),deptno
1,9,7,10
2,9,7,20
3,6,4,30
---xx----
where as in the o/p of user's question
we have
empno,max(sal),min(sal),deptno
1,9,3.5,20
2,8,4.5,20
3,6,4,10
here empno=1 his max(sal)=9 from deptno 20 and min(sal)=3.5 then its deptno=? actually we r giving a correct information but client will get confused max(sal) and min(sal) r both from 20 or different departments.
-----xxx----
even though client is expecting the same output then laxmi answer is correct

hai first use the copy stage. from that take three links.
in that first and second links are connected to aggregator
stages.
agg1-- max and min for sal group by empno...
agg2--max only group by empno...
then use lookup for agg2 and third link of copy stage...
in lookup join max{sal} to sal and get deptno...
finally, o/p links from agg1 and lookup are joined by
lookup.. join by max{sal}....
then u can get the desired o/p...
