I have a scenario like
Deptno=10---->First record and last record
Deptno=20---->First record and last record
Deptno=30---->First record and last record
I want those first and last records from each department in
a single target. How to do this in DataStage, any one can
assist me.
Thanks in advance.

1.
Source--->Sort stage--->copy stage======>(SRC1,SRC2)
From copy stage we have to take two source stages
(SRC1,SRC2)
SRC-->Removeduplicate stage(in this we can get first
record from each dept--> Duplicates To Retain=First)
SRC2--->Remove duplicate stage(in this we can get last
record from each dept--> Duplicates To Retain=Last)
using funnel we can add these results.
2.
source->sortstage->removeduplications->dataset
in sortstage->create key changecolumn=true
this will set '1' for 1st records and '0' next duplicate
records.
after
removeduplicates stage(key columns=Deptno, CreateKeyChange
Columns)->duplicates retain:-last
we can get last(CreateKeyChange is zero and from all the
duplicates in that group, we are retaing last record) and
first(CreateKeyChange is 1) record group(Dept) wise.
