Hi Achoudhr,

here u go,

sq--->agg----->target

In agg dont use group by on any port and take output
columns for both id & date ports, use 'min' function in
outpput expression and connect output ports to desired
target columns.you will get only one output row that is 101
2/4/2008.

note: if u use group by mapping outputs 3 rows.

Answer / mitesh gaur

I think there is no need of using any aggregation. It's very
straight fwd, just sort the data on date and fetch only
first record.
Add the below query to source qualifier's SQL OVERRIDE
and that will be your result - (lets say table name is TmpTab)

select * from (select * from TmpTab order by date) where
rownum = 1;

now connect id, date to target.

Answer / rob

Add the below query to source qualifier's SQL OVERRIDE
and you will get the required output

select * from (select min(to_date(date,'dd/mm/yyyy'))as
d,id from emp
group by id order by d)where rownum =1;

source-->SQualifier(with query)----> target

Answer / parthiban

S->SQ->SRT->EXP->FIL->TGT

Sort on date Column

In Expression, Create variable ports for partition
V_Currdate = date
V_Flag = IIF(V_Currdate = V_Prevdate, V_Flag+1,1)
V_Prevdate =date
O_Flag = V_Flag

In Filter, Filter where O_Flag =1

Answer / azhar

Simple use sql override query:

select top1 * from TABLENAME order by ID,DATE

Answer / deepak

SQ --> Sorter (sort on date desc) --> Aggregator (select no ports so it will always return last row) --> Target

Answer / bidhar

I think you can get this by SQ Override query itself.

SQ->Exp->Target

SQ Override Query:

SELECT ID,MIN(DATE) FROM TABLENAME GROUP BY ID.

Let me know if i am wrong.

Answer / kalyan

I guess the below logic will solve this question..

Sq -> Expression T/R -> Aggr t/r -> Target

Create a constant port in Expression t/r and then pass the 3
fields id, date & const port to the aggregate t/r... Create
a new port calculating mindate.. Now do a group by on the
Const field ; connect id & min Date fields to the Target...

FYI, If u don't apply group by on any column of the table ;
can not calculate the Aggr values...

Please correct me if I am wrong...

2,if we have 3 pipeline containing 3 targets and each target is connected with diff sequence generator ,let us assume first target is populated with seq no1-9,so what would be the number generated by other two sequence generator?what is the diff in o/p if when we use reusable sequence generator?what would be the diff if we place expression in between target and sequence generator?
