Using Source Qualifier Trnsformation ,
Explantion:
1.Take 2 Source Qualifier Transformations,and
2.One sq ports connect to Target(Unique Target) then Write
a SQL Query (sqlOverride) ,
SELECT DISTINCT EMPNO,ENAME
FROM EMP;
3.TAKE ANOTHER SQ AND CONNECT TO ALL PORTS TO TARGET,THEN
DEVELOP THE SQLOVERRIDE,
SELECT * FROM EMP WHERE ROWID IN(SELECT ROWID FROM EMP
MINUS
SELECT MAX(ROWID) FROM EMP
GROUP BY EMPNO,ENAME)

Answer / shiva

s-->sq-->agg-->rtr-->tgt1
'--> tgt2

in aggr take two ports count(*)=1
count(*)>1 take group by on column


send this to rtr(create 2 groups in rtr)

Answer / mohan

Here is the minor modification on Answer #6 posted by me,
SQ-->Sorter-->Expression-->Router-->Targets

Sorter Transformation: Sort by key column(EMP_ID)
Expression Transformation:
V_Match(variable port) =IIF(EMPNO=V_OLD_EMPNO,1,0)
V_OLD_EMPNO(Variable)= EMP_ID
O_EMPNO(output)= V_MATCH

Router Transformation:
create two groups under groups tab,
Original : O_EMPNO=0
Duplicates: o_EMPNO=1 

Answer / naresh araveti

source> dynamic lookup>router,2 conditions 1. condition
if column_lkp port is null then insert into target1(unqie)
2. condtion if COLumn_lkp port is not null then insert into
target2(duplicates)

Answer / ram mohan reddy

we can do this process by 2 ways ....
1)by dynamic lookup option in lookup(new lookup row) we can
load duplicate rows in one target table and unique rows in
one target table
do to this we need to have router transformation (add to
group ports one is for unique(new lookup row=1) and other is
for duplicate(new lookup row =2))after the lookup trans.
2)we can perform this by aggregator transformation using
coutnt(*) >1 for duplicate rows .here also we need to use
router transformion.

Answer / venkat

S->S.Q->Aggr->Rtr->T1
->T2


Where Aggr take group by option
Rtr group1 condition reccount>1..........>T1
Rtr default group to....................>T2


T1 records are unic records
T2 records are duplicate records

Answer / mohan

SQ-->Sorter-->Expression-->Router-->TGT

Sorter: Sort by key column(EMP_ID)
Expression:
V_OLD_EMPNO EMP_ID
V_Match IIF(EMPNO=V_OLD_EMPNO,1,0)
O_EMPNO V_MATCH

Router:
create two groups under groups tab,
Original : O_EMPNO=0
Duplicates: o_EMPNO=1

Answer / vaas

Hi All,

One tbl has duplicate values means it does not has PK.In
this case can we use dynamic lookup.
