Answer / hunny

Try This :

Source -> SQ -> Sorter(Sort by Ascending on Key) -> Aggregator(Group by key Column,var=count(key colmn) - > Router(var = 1) -> Unique Target and (var > 1 ) -> Duplicates.

Make sure the Datatype for Var is not String in this scenario else will encounter operands of ambigious types mismatch error.

Answer / nag

Hi,

I think this scenario will help u.
Source - SQ Trans(2 Instances)-target(2 different targets)

In one of the Instances of SQ Trans write this Query:

select distinct <field name>......from <table name>;

Note:- It fetches only unique records.

In another Source instance write the following query:

select * from <table name> where rowid not in (select max
(rowid) from <table name> group by <field name>);
ex:- select * from emp where rowid not in (select max
(rowid) from emp group by ename);

Note:- It fetches only duplicate records.

then pass the fields to the targets(u should take different
targets).

I hope this will work.

Thanks and Regards,

Nag

Answer / usha

1st method by using expression transformation by adding
variable ports.


2nd method by using dynamicLKP we can load UNIQ records to
one taget table and DUPLICATE records to other target table

newLKProw=1(Insert)

newlkprow=0(if there is no difference in associate ports)
UNIQ records

Answer / chetan

I/p
A
B
B
C
D
D

need to load A.C in one tgt and B,B,D,D in another target table.

SQ o/p should be given to aggregator. group by first column.create another port(v_count) with count(*).

SQ o/p should be passed to joiner to join aggr and SQ(source).

o/p looks like after joinning
A 1
B 2
B 2
C 1
D 2
D 2

use router to route v_count=1 and v_count=2 to different targets.

Answer / naveen

Answer #3 is correct by Nag.

Addition to above second query for duplicate records, will
return unique records for each duplicate records.

if you need all duplicates records thn follow the below
query.

select * from emp
where empno in (select empno from emp group by empno having
count(empno)>1)

Answer / bala

in router count(*)=1 for good record

count(*)>1 for duplicate record

Answer / apoorva

question:

shouldn't the condition for unique_record be >= ??

Answer / haaris

If the source is RDMS, then you can write analytic function in the select statement to assign count to each row. And use this count column to route the records to respective target.

If the source is a flat (this is generally asked in interviews), then you can use aggregator to assign count to each row after grouping based on the key and use joiner to join back to source records that way all the rows coming from the SQ will have respective counts. Use router to route them to respective targets.

Answer / amedela chandra sekhar

sq-->Aggregator-->Router-->target

select group by for port name empno

in aggregater t/r take 1 output port and give condition like

select group by for port name empno

varcount---->count(*)



connect this one router and in router take 2 groups and
give condition like

uniqe_record :varcount=1-----for unique

duplicate_record :varcount>1 ----for duplicate


and connect that groups to target.

u will get result.

Answer / chandra

FIRST WE TAKE SORTER Tr ,BY USING THIS WE CAN RETRIEVE
UNIQUE RECORDS...NEXT
WE TAKE EXP Tr IN THAT INSERT NEW OUTPUT PORT ..,IN THE
OUTPUT PORT EXPRESSION WRITE COUNT FUNCTION AFTER THAT TAKE
FILTER Tr IN THAT PUT THE CONDITION AS
IIF(COUNT>1,TRUE,FALSE)THEN CONNECT TO TARGET......


SQ-->SORTr-->TARTr1(UNIQUE)
-->EXPTr-->FIL Tr-->TAR Tr2(DUPLICATES)

write sql query following table amount year quarter 1000 2003 first 2000 2003 second 3000 2003 third 4000 2003 fourth 5000 2004 first 6000 2004 second 7000 2004 third 8000 2004 fourth i want the output year q1_amount q2_amount q3_amount q4_amount 2003 1000 2000 3000 4000 2004 5000 6000 7000 8000 can anybady help me to achieve the aboue result by using informatica. thanks in advance.
