Answer / shridhar kasat

For Unique and Duplicate , we can go for same flow :

Source-->SrcQualifier-->Aggregator(group
by this column and find count also)--> then use joiner (use
the column from Source qualifier and join the data from
Aggregator as source qualifier.col=aggregator.col) -->
Router (insert into t1 for count>1 and for count=1 insert
into t2). t1 is for duplicate records and it will cintain
1,1,3,3 and t2 will have 2,4.

Records in Source Q :
col
1,1,2,3,3,4

The records after agregator will look like this :
col count
1 2
2 1
3 2
4 1

Records after Joiner : source q.col=aggregator.col
col count
1 2
1 2
2 1
3 2
3 2
4 1

These records will flow in router and we define two groups;
one for count>1 (for duplicates record) and second for
count=1 ( for unique record)

Hope this answer suffice your requirements.

Shirish,

Part 1 of your answer is not correct. If you use distinct
option in sorter you will get all the distinct values even
for the duplicate. i.e if the values are 1,1,2,3,3,4, you
will get 1,2,3,4 in target.

Part 2 of your answer will do all the trick for duplicate
and unique ones. If you use group by and count the number
of occurences you will get 1 as the count for unique values
and more than one as count for duplicate values. Pass those
records with count 1 to 1 target and the other to the 2nd
target.

Hope this helps.

Answer / shirish

1.For unique: Source-->SrcQualifier--> sorter (use distinct
option)--> Target
2. For duplicate : Source-->SrcQualifier-->Aggregator(group
by this column and find count also)-->filter(use count
greater than 1 )--> left outer join with source qualifier --
> target 2.
Hope i am clear.
