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.

Answer / ashok
Source--->Sort stage--->copy stage
From copy stage we have to take two source stages
(source1,source2)
source1-->Removeduplicate stage(in this we can get first
record from each dept)
source2--->Remove duplicate stage(in this we can get last
record from each dept)
using funnel we can add these results.

Answer / d anil babu
take source--->copy---->remove dupli stage---->
----->remove dupli stgae-->funnel-->dataset
in first remove duplicate stage select duplicate retain first
in second rmd select duplicate retain last and in funnel u
have to select the sort funnel

Answer / amjad pasha
SOURCE ---> SORT STAGE(sort key mode = sort, create cluster
key change column and create key change column should be
false) ---> COPY STAGE ---> (2 REMOVE DUPLICATE STAGES)
REMOVE DUPLICATE STAGE_1 (key=dept and Duplicate to Retain
= First) AND REMOVE DUPLICATE STAGE_2 (key=dept and
Duplicate to Retain = Last) ---> FUNNEL STAGE (Funnel
Type=Continues Funnel) ---> TARGET

Answer / prabhu
source->sortstage->removeduplications->dataset
in sortstage->create key changecolumn=true
after
removeduplicates stage->duplicates retain:-last
we can get last and first record group wise.

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.

Answer / naga
take a sequential file and give the output link to copy
stage and from copy stage give one output link to head
stage and one output to tail stage and in head and tail
stages give no. of partitions per record =1 and give the
output to funnel stage and give funnel type = sequence and
mention the link order to displays which records first and
give the output link to dataset and you will get the output
you want

Answer / naga
take sequential file and give its output to copy and copy
it to two datasets.in one dataset select the partition on
deptno type=modulus and perform sort and select both stable
and unique you will get first redcords and in another
dataset select partition on deptno and type modulus and
perform sort and select only unique and give give both
dataset outputs to funnel and give its output to dataset

hi All, i have one scenario like if source--->transformer-->2 target sequential files the 1 st target sequential file is loads the data from source and 2nd target sequntial file contain the 1st target total record count,and file name of 1 st target seq file and timestamp seperated by delimeter for example if source have 10 record the 1st target seq file hav 10 records and 2nd target seq file example 10|xyz.txt|20101110 00:00:00 could you please help me out how can i implement in datastage job.
