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

10 Answers   Cap Gemini, Wipro,

Suppose we have a (assume relational) source table Product_Id Month Sales 1 Jan x 1 Feb x . . . . . . 1 Dec x 2 Jan x 2 Feb x . . . . . . 2 Dec x 3 Jan x 3 Feb x . . . . . . 3 Dec x . . . . . . and so on. Assume that there could be any number of product keys and for each product key the sales figures (denoted by 'x' are stored for each of the 12 months from Jan to Dec). So we want the result in the target table in the following form. Product_id Jan Feb March.. Dec 1 x x x x 2 x x x x 3 x x x x . . So how will you design the ETL mapping for this case , explain in temrs of transformations.

Source Qualifier is an active t/r but there is no change of row count then y should we called it active t/r & Router , sorter some times no change in row count then Y we called its active t/r?

My Source qualifier has empno, sal. Now my mapping is like SQ(EMPNO)->AGGR->EXP->TARGET SAL ------------>TARGET ? means only one source qualifier has 2 columns like empno, sal. connected to same target as shown in above mapping.Is this mapping valid or any issues are there if we design like this?
