Answer / pavana

You can use sequence generator and then in exp trn, use a
variable which reads the 1st number the seq generates and
use filter transformation and take only 1st generated row
and +10th record.

Answer / jaybrata

have you guys heard of Informatica CUME() function?
Don't use seq generator, aggregator, sq override nothing.

Simply in a expression, calculate,
v_cume = CUME(1)

and after that in a filter use,
v_cume=1 OR v_cume=10

Answer / prakash kumar kumhar

ower write sq ("select *from <tableNmae> where rownum <= 10;")
than use two aggregation transformation (in first use first(),and in second use last() for each column)from sq to target.
note: use two target table in which u want to load that two records.

Answer / sathish

source may be flat file or database just you use sequence ganarater then filter copy the nextval port to filter write condition nextval=1 or nextval=10 you get only 1 and 10 th records

Answer / prasuna

Ya ..that is right in case its a table..in case of flat
file..i think we cannot use Over ride ...i think using
sequence generator or by finding rownum in Expression
transformation ..after that by filtering two rows ..we get
the output..

Answer / chandrasekhar

You need to use MOD function based on you can filter it
out.. then you will get 1..10..20..30....like we will get it

Answer / chandra

override source qualifier
SELECT E.* FROM(SELECT ENAME,SAL,ROWNUM R FROM EMP) E WHERE
R IN (1,5);
HERE I TAKE EMP TABLE

Answer / eswar

As Prakash said
ower write sq ("select *from <tableNmae> where rownum <=
10;")

Instead of using Aggregator its better if we use Router
Transformation, wherefrom we can route the rows to target
(s).

note: use two target table in which u want to load that two
records

Answer / prasuna

sorry,i need here..for example if i have 50 Records..in that
i need 1st and 10th..

Answer / sujana

i think v shud use FIRST and LAST functions in aggregator..

generate Unique sequence numbers for each partition in session with Unconnected Lookup ? Hi All, Please help me to resolve the below issue while Applying partitioning concept to my Session. This is a very simple mapping with Source, Lookup , router, and target. I need to Lookup on the target and compare with the source data, if any piece of data is new then Insert, and If any thing change in the existed data then Update. while Inserting the new records to the target table I'm generating sequence numbers with Unconnected lookup, by calling the maximum PK ID from the target table. The above flow is working fine from last one year. Now I wish to apply the Partitioning concept to the above floe(session) At source I used 4 pass through partitions.(For Each partition different filter conditions to pull the data from source) at Target I used 4 passthrough Partitions. it is working fine for some data, but for some rows for Insert Operation , it is throwing Unique key errors, because while Inserting the data it is generating the same sequence key twice. In detail : 1st row is coming from 1st partition and generated the sequence number 1 for that row. 2nd row is coming from 1st partition and generated the sequence number 2 for that row 3rd row is coming from the 2nd partition generated the sequence number 2 again for that row. (it must generate 3 for this row) the issue is becuase of generating the same sequence numbers twice for different partitions. Can any one Please help me to resolve this issue. While Applying partitions how can I generate a Unique Sequence numbers from Unconnected lookup for Each partitioned data. Regrads, N Kiran.

Hi, In Router transformation I created two groups . One is Passthrough=> True Second one is CorrectId’s => Invest>50000 Here I have one doubt. Can’t I treat default group as Passthrough group (fist group) . Is there any difference between default group and Passthrough group in this scenario? Let me know if you want more information about this scenario. Advance thanks.
